Bellew took advantage of his hurt opponent and cracked Haye again to the tune of the bell signaling the end of round which coincided with the start of referee Howard John Foster's count.
Froch was on commentary duty for Sky Sports and he delivered a line after the fight that paints a sad picture of where Haye's career lies. Bellew lands another flurry of punches that sees his right hand finding the mark on Haye's jaw.
Reacting to the win in his post-fight interview, Bellew dedicated the victory to his late brother-in-law before reflecting on the fight.
Who could Tony Bellew fight next?
One driving question that surrounded David Haye v Tony Bellew II was how exactly they had managed to sell a squeal on this fight. Here Haye began dragging a lame leg around as he seemed to struggle to move laterally-fighting with one leg much like their first encounter.

The U.K. and European Union parliaments also want Zuckerberg to answer their questions publicly, though he has so far declined. He said, "There will always be a version of Facebook that is free", he said, leaving the door open for paid alternatives.

Bellew stopped Haye in the 11th round some 13 months ago and again boxed a clever fight.
Paul Butler (26-1) faced Emmanuel Rodriguez (17-0) for the vacant IBF world bantamweight title but fell short to a classy Rodriguez, suffering a unanimous decision loss, a performance in which Hearn praised the visitor. "We'll never be friends but I respect him", he said, adding he begged Haye to quit boxing in the immediate aftermath.
This time there was no injury to blame, but Haye was already going back on his own word that he would quit not only if he was beat, but even if he won and didn't impress. I couldn't quite make it happen, and you know, everything happens for a reason, and he was victorious tonight.
