You're talking about that weird video where someone replays and reverses and fast forwards over some of the action before DDP drives Sean into the fence, then stands up, hitting his head into Sean's eye, and Sean had blood all over his face, right?
That happened 40 seconds into round 4, at about the 4:20 mark.
Problem with that is, at 4:39, only 21 seconds into the round, DDP throws a left right, and the right glances off of Sean's face.
Sean blinks it out twice, showing he did get punched in the eye.
Aaaaand he's bleeding.
See, before the headbutt.
Headbutt surely either made it worse, or at the very least, spread it all over his face. Maaaybe it made a second cut. But Sean was opened by a punch
I'll wait for your further backtracking, since you can't even admit you're wrong
