These guys get concussions amd are expected to fight on, crazy when you think about it. Some of these guys may get 2-3 concussions a fight.
I remember when morales and barerra fought, I think the 2nd time, morales is against the ropes and gets caught with a right, his hands clearly drop, his head drops, and his eyes shut, and he begins to fall down.
Out of no where his head pops up and he starts swinging back. He clearly was knocked out for a split second than came back to life. That was nuts.
if you to the 4:00 minute mark, you'll see what I was talking about.
