2.50 am

The next fight should be interesting. Gilberto Ramirez, from Mazatlan, Sinaloa, Mexico, is highly rated with a gleaming 30-0 (24) record. He’s someone James DeGale has been looking at as a potential foe as the Briton plots a course towards a world title. Ramirez’s opponent tonight is Maxim Vlasov is 30-1 (15). The Russian’s only loss came against Isaac Chilemba in 2011. Here we go…

2.58 am

Neither made a breakthrough in the first round, Ramirez, a southpaw, advanced, squaring up at times, but landing little of note. Vlasov looked sharp with clusters of lighter punches.

03.02 am

Brandon Rios is dancing in the changing room. Ready to rumba… (Forgive me).

03.08 am

Vlasov jerks himself bodily away, a sign he’s starting to feel the weight of those punches. After the first four rounds Ramirez is starting to take over.

03.11 am

The referee warns Ramirez to stop his shots straying below the belt.

03.15 am

We’re into the sixth round and Vlasov is starting to perk up.

03.20 am

03.25 am

The Russian sneaks in an uppercut in close and lashes in a right, forcing Ramirez momentarily on to the back foot.

03.30 am

Vlasov holds his ground more in the ninth round, both look like they’re flagging as they get caught up clinches. Gilberto’s hooks and uppercuts cleave round Maxim’s guard.

03.33 am

04.10 am

Alvarado can’t answer the bell for the fourth round. The fight is over. Rios roars to celebrate. “I’m back,” he shouts to the crowd.

04.12 am

Rios did look relentless, fast and powerful. But with legal troubles looming over him, you have to wonder how well Alvarado’s preparations had gone, what his mental state was in the fight and how much the wars of his career have taken out of him.

04.20 am

“I listened to my corner. I put pride aside,” Rios declares. “Whatever he did, I was practising for and I came out victorious. That was the performance I want. I’m still young in the sport. This is a new me right now. This is a new ‘Bam Bam’. I don’t care who it is, I just want to get back to the top.”

04.27 am

In a distressed, confusing post-fight interview, Alvarado says he suffered an eye injury at some point in the fight. But he seemed adamant that he would box again.
