Darren Barker: My mum graduated as a mature student. We was up at the Southbank, and my phone rang, and it was Eddie [Hearn]. I was walking over the bridge, back to Embankment. โ€œGood news โ€“ย got the fight with [Daniel] Geale.โ€ โ€œRight โ€“ย that is it. This is it. This is it now.โ€ I was so excited โ€“ I didnโ€™t even ask how much I was getting. I didnโ€™t care. I was buzzing.

Eddie Hearn: Tony had said to me, โ€œWeโ€™re out of contract โ€“ย would you be interested in promoting Darren Barker?โ€ He was, effectively, my first signing. You never knew when it would be over. He was becoming so disheartened with the injuries, and it looked like the big paydays were eluding him. โ€œWeโ€™ve got a title shot โ€“ย Gennady Golovkin.โ€ โ€œNo thanks.โ€ โ€œBut they donโ€™t even really want a purse.โ€ I subsequently found out why.

Tony Sims: โ€œMate, thereโ€™s no fucking way youโ€™re putting Darren Barker in with Gennady Golovkin unless youโ€™re giving him the minimum of a couple of million.โ€

The [Sergio] Martinez fight was a big learning fight for him. It was the best thing weโ€™d done; after that fight he knew that he could mix at world level. When this fight come about he knew he was ready.

By then, weโ€™d had to halt the running. He started swimming, and did a lot of yoga and stretching and exercises. He was still sparring and doing the pad work the same.

Hearn: He also worked heavily on the mind. Physically, he was good. He was in a really good place going into the fight.

Barker: Laws of attraction โ€“ย I remember walking down the stairs at the gym, and bumped into this geezer. He was a yoga bloke whoโ€™d had two hip replacements; Iโ€™d had hip operations. He started saying how yoga really helps him. Usually when Iโ€™m training Iโ€™m in the zone and donโ€™t stop to talk to anyone โ€“ Iโ€™m a miserable bastard. But for some reason I started talking to him. Wayne Leal. In sessions he used to do guided meditations. If Iโ€™m deadly honest heโ€™d feed me a load of bollocks making me feel a million dollars. Iโ€™d feel so calm. It was so beneficial.

Iโ€™ve never approached a camp with such professionalism and intensity. You could say Iโ€™d overtrained, โ€˜cause when Tony would say, โ€œGo home and have a restโ€, Iโ€™d do extra sprints in the pool. I shouldnโ€™t have been running, because of my hips, but I ended up doing a few hill sprints. I was a man possessed.

Hearn: We stayed at a new hotel, The Revel [Casino], which was unbelievable. I did not have a clue what I was doing, in all honesty. We were just on the blag โ€“ย to get the fight in the first place; in Atlantic City โ€“ย and thatโ€™s one of the reasons it was so special. It was me, Darren, Tony and the team out there rolling the dice.

Sims: It was like one of them hotels you see in Vegas. I remember Gary Shaw driving around the hotel in one of them mobility scooters. It was that big.

Hearn: Heโ€™s got a very close family. They all started arriving one by one in Atlantic City โ€“ย his dad Terry was a good, good boxer for the Repton as well. With what theyโ€™d been through with Gary [Darrenโ€™s late brother], Iโ€™m sure the whole family felt him with them that week. He probably brought 400 or 500 over.

Sims: A few of the fighters come over. Lee Purdy; Martin Ward; Luke Campbell; Kevin Mitchell. I remember walking along the boardwalk the day before the fight, with Ryan Taylor, and this big guy was walking towards us. โ€œThat geezer looks like Larry Holmes.โ€ As he got nearer to us, it was Larry Holmes.

โ€œIโ€™m here to watch the fight tomorrow, and the IBF are presenting me with a belt. Listen, tell [Barker] to use the jab โ€“ย itโ€™s all about the jab.โ€ As he was talking to us, we looked round and Roy Jones Jnr was walking along with his boy. Ryanโ€™s walked up to him, โ€œCan I have a photo with you?โ€ โ€œJust let me have a photo with my idol first,โ€ and pointed to Larry Holmes, โ€œand then Iโ€™ll do one with you afterwards.โ€ Then we all had a photo together. It was a bit crazy.

Barker: I felt experienced, because Iโ€™d had that kind of build-up to the Martinez fight [in 2011]. It wasnโ€™t alien to me. โ€œIโ€™ve done all this before.โ€ I felt a lot more relaxed, and focused. I felt a lot more mature, and a lot more self-assured. After the Martinez fight I felt I belonged at that level.

Hearn: When we were about to leave for the venue [the Revel Resort] on fight day, he had a little bit of doubt in himself, and I remember him going to have a session with Wayne to get himself mentally back.

Barker: For 13 weeks and six days I was the most confident man there was. Nobody was beating me. On the day of the fight โ€“14 weeks since Eddie called me โ€“ I had a bit of a meltdown. Wayne come to the room, and we did this guided meditation. By the end of the session I was back on it. He was beneficial to me that camp, absolutely.

Hearn: It was a tiny, tiny changing room. Really tense. He put the gloves on a bit late. Heโ€™d keep shaking his head. โ€œNah, they donโ€™t feel right; they donโ€™t feel rightโ€. They want him to walk in two or three minutes. Itโ€™s all over the place. โ€œYouโ€™ve got to walk now.โ€

Barker: Straight after the weigh-in, โ€œI ainโ€™t going to no fightersโ€™ meeting; I ainโ€™t trying on no gloves; I donโ€™t give a toss; theyโ€™re all the sameโ€. Well, I was massively wrong. Tony tried them on in the meeting.

I had my hands wrapped. Very relaxed; it was good. I had a couple of the boys from the gym in there; my brother [Lee]. Michael Buffer poked his head in and we had a gag with him. I was focused; all the hard work was done. I was [also] properly nervous โ€“ย it was always the time I felt most nervous, when it was time to get gloved up.

I couldnโ€™t get my whole thumb in, so it felt really, really tight and uncomfortable. โ€œFucking hell, Tone, these donโ€™t feel too good.โ€ I started doing the pads. โ€œI canโ€™t wear these, Tone.โ€ Iโ€™d never done this before โ€“ ever.

Sims: โ€œWeโ€™ve only got two pairs of gloves here, Dal. You gotta wear one or the other.โ€

Barker: Weโ€™re getting close to the ring walk. โ€œI put them gloves on and theyโ€™re fucking worse โ€“ย theyโ€™re worse than the others ones.โ€ Iโ€™ve gone back to the original pair, and Iโ€™m hitting the pads, hoping theyโ€™d loosen up. They didnโ€™t, but I knew that once the bell goes all of that would go out the window. But at the time I was thinking, โ€œThis ainโ€™t goodโ€.

Sims: โ€œOnce you started punching with them youโ€™ll forget about how uncomfortable your thumb is.โ€ Which he did do. Little things like that when youโ€™re nervous in the changing room play a big part in how youโ€™re thinking at the time. You can go in the ring with bad hands; once the adrenaline goes you donโ€™t feel anything. I knew once he got in there he wouldnโ€™t even think about the thumb.

Hearn: Walking out after that, I thought, โ€œI donโ€™t fancy our chances hereโ€. I donโ€™t know whether it was nerves; the gloves. But, he wasnโ€™t comfortable. It was a real unnerving moment. โ€œThis isnโ€™t right here.โ€

Barker: Iโ€™ve got to thank Sky, and Ed Robinson, who produced a documentary before the fight. They finished it with the U2 song [I Still Havenโ€™t Found What Iโ€™m Looking For]. โ€œYou know what? Iโ€™m going to use it as wellโ€, and it really pumped me up. It was a powerful ring walk.

Sims: He boxed well, right until he got caught. He was in front of points. He was very aggressive โ€“ย he wanted to win the fight for Gary, and we all knew what heโ€™d gone through to reach that stage. It was only a couple of years before he never wanted to fight again. A little bit of his boxing ability he left behind, but the aggressiveness of it, I think the American judges like. He was a lot more aggressive than Geale, which maybe took Geale by surprise.

Barker: I didnโ€™t take into account how slippery and how quick he was on his feet, so I was falling short, quite quickly, with my shots. โ€œIโ€™m going to have to really get close to him.โ€ The plan was always to be aggressive, but I went all-out brawling with him, to get my feet close to him; get on his chest.

Hearn: Darren started well, and he was definitely edging the fight. I was sitting next to my dad [Barry]. โ€œBarker round; Barker round.โ€ We were pretty pleased with the start.

Barker: I knew it was comfortable, considering it was a fast-paced fight. Then [in the sixth round] I got caught with an absolute beast. Usually with body shots thereโ€™d been a delayed reaction, but there wasnโ€™t with that โ€“ย it was fucking instant pain. I just dropped, and thatโ€™s where all the visions; the thoughts; the memories [of Gary] come flooding back.

Hearn: At that point weโ€™re winning. It came out of nowhere โ€“ย a big body shot to the solar plexus, and he went down. He was facing where I was sitting. โ€œHeโ€™ll get up.โ€ Then it got to six or seven, and he was kicking his legs on the floor, and I thought, โ€œFuck, heโ€™s not gonna get upโ€.

Barker: I could see him. I could see visions of him. When my headโ€™s on the floor and Iโ€™m kicking my feet on the canvas, Iโ€™m watching him saying, โ€œCome on, come on โ€“ get upโ€. Completing it for both of us โ€“ย he played a massive part.

Sims: He had his back to me, so I didnโ€™t know whether heโ€™d been hit with a low blow. Then Lee, his brother, the first time heโ€™d ever been in a corner โ€“ย when Darren was on the floor he was jumping all over my back to stop the fight, and I had to push him away and tell him to be quiet.

I was seeing whether he was going to get up or not. He got up at the count of nine; sometimes they wave it off [in the UK] at that stage.

Barker: I was absolutely unaware of the count that was going on, โ€˜cause of the pain and the visions. I donโ€™t know how close I was to not getting up but there was definitely thoughts of fucking it off. I was crippled; I couldnโ€™t stand up straight. It was agony;ย it was awful. It was a poignant moment in my career. Everyone always says, โ€œI donโ€™t know how you got up from that body shotโ€, and I donโ€™t, if Iโ€™m honest. I just somehow rose.

Hearn: He beat the count and was half bent over, and was looking around to see how longโ€™s left. There was a flurry at the end of the round where he went toe to toe, and then the bell went and he banged his chest, to say, โ€œLetโ€™s fucking have itโ€. We were so pumped at that moment. That may have been just as important as him getting up. That changed the momentum.

Barker: It was about trying to get my composure back, and weather the storm. I knew I had to start throwing back, because I hadnโ€™t for a while, and I could see the referee [Eddie Cotton] getting close. I landed a couple of shots, and then the bell sounds โ€“ย I remember thinking there was a bit of a shift in power. He was on the brink of victory and I was on the brink of defeat and right at the end [of the round] I come firing back with some shots.

Sims: He just about got through the round and started firing off again, so I knew that he was alright when he come back to the corner. He made it to his feet and he cracked on. I could see the deep will in him.

Barker: The seventh round was probably me best round. After that I had to dig it out, โ€˜cause it was tough in there. It was high tempo; gruelling, physically and mentally. He was a fit bastard.

Sims: He was boxing well and putting combinations together well. I liked the way he was fighting.

Hearn: Going into that 12th round, this fight is so close โ€“ you have to win this round. โ€œDarren,โ€ โ€“ he looked right at me โ€“ โ€œyouโ€™ve got to win this round.โ€ I was losing my shit the whole fight; my heart was beating out of my chest.

Sims: There was a couple of rounds that were touch and go. Geale must have known that he was slipping behind on the scorecards, and started putting a lot more into it. Both of them was biting down on their gumshields, staying ring centre and throwing a lot of punches. It became a really entertaining fight to watch, but I believed when the last bell went that Darren had won the fight. Eddie said to me, โ€œItโ€™s really closeโ€. When they went to split decision you thinkโ€ฆ

Barker: I knew it was gonna be a split-decision. I could tell, from the tension. As he says, โ€œAnd the newโ€ [Barker won via scores of 114-113, 116-111 and 113-114], I jump up, but then floods of emotion hit me like a ton of bricks. Initially I was very sad โ€“ย it was like I was letting go of my brother. Thatโ€™s why I fall to the floor and Iโ€™m crying my eyes out. โ€œI hope Iโ€™ve done you proud โ€“ย Iโ€™m sorry Iโ€™m letting go.โ€ Looking back, of course Iโ€™m not letting go, but it was really vivid pain and grief that hit me in that moment. I donโ€™t really remember the fight but I vividly remember my emotions afterwards.

Sims: It was very emotional. We all had a tear rolling down our cheek. It was the journey weโ€™d all been through. Gary was a fantastic prospect as well; we was all at that boxing show the night heโ€™d died. It seemed like the whole of Britain was behind [Darren] and wanted him to do well.

Hearn: Itโ€™s definitely the greatest feeling Iโ€™ve had in boxing. When you look back on the emotions in that ring, it was unbelievable. Unbelievable. Darren was on the floor, and Tony jumps on him. โ€œYouโ€™ve done it.โ€

Barker: People thought I was just a tidy boxer but if it got tough I wouldnโ€™t be able to stick around. That fight I proved I could hold my own, so I was proud of myself.

Sims: It was one of the best nightsย โ€“ weeksย โ€“ Iโ€™ve ever had. I still vividly remember most things that happened.

Hearn: When he achieved that, the comfort that he received โ€“ย itโ€™s so rare. Very few achieve their dreams or their potential; even those who do struggle [in retirement]. Thereโ€™s very few fighters Iโ€™ve represented who have retired mentally and emotionally [content].

Barker: I wish I savoured those moments a bit more. I wish I could go back.
