1 Jordan Gill W KO 9 Karim Guerfi

In a year featuring some of the most dramatic one-punch knockouts we have seen for some time, the number one spot ultimately goes to Jordan Gill and the right hand he pulled from nowhere to extinguish the attack of a buoyant Karim Guerfi in February. This shot, unlike the others in contention, happened to be thrown when Gill was seemingly on his way to being stopped himself and therefore the shock of it landing, and the damage it caused, was felt tenfold, both by Guerfi, who was rendered unconscious by it, and all who watched it unfold in real time.
