Are you guys seriously blind? Their FEET WERE NOT TOUCHING!
The white in between their shoes is the white logo of the canvas! It's not Zab's shoe.
It's not a big deal. Floyd got hit, and was knocked down. It's not the end of the world. I have seen Floyd hurt much worse than that and not go down. So what, he ended up winning the fight. Fighter get hit, they can be knocked down or even out. They are exchanging punches with other professional boxers. In the end, it meant nothing. However, it was clearly a knockdown.
