Roy got ko'd by a rabbit punch.

I just dont get how Roy looked so good vs Lacy only to get dropped by that janky ass right hand i mean.... at one point in the Lacy fight Roy was dodgin punches while talkiin to cats in the crowd

After looking at the video a few times now it still looks to me that Danny Green landed an unintentional rabbit punch. The shot seems to hit Roy in the back of the head. His reaction to the shot kind of confirms it landed on the back of the head. His equilibrium was thrown off and he couldn't regain his balance with Danny Green throwing furious blows his direction. I think Roy should have been given time to clear his head because regardless if it's intentional or not, the shot landed on the back of his head which is illegal. That's like ko'ing a fighter with a low blow, imo... lol Zab Ko'd a fighter with a low blow
