I've seen delayed reactions to KO's before . That one looked a little iffy but it could just be a case of glass jaw.
he didn't fall like a sack of potatoes..but then again it COULD have been a delayed reaction. I don't think it was though. You see delayed reactions mostly from body shots.
Shady business happens in boxing all time. All the time. This is very suspicious, BUT not the most suspicious I have seen. It could very well have been a case of "Likar Ramos."
I see no reason, no reason at all why youd go down and stay down in the 1st round unless you were really hurt or knocked out. But like somebody has said, it looks straight up iffy.
Surely as a boxer he should have known better. Thats like someone who has never participated or seen the sport trying to act ko'd.
