He couldn't swallow his own saliva anymore, so I think it's pretty much broken. Still we have to wait for the tests to confirm the injury, but I do think he has a broken jaw.
I highly doubt a guy thats WINNING, a fight ...would give up a mega fight with canelo.... to FAKE a injury.. vs a guy he is man handling
what you say makes sense but we shouldnt forget Ortiz's past history:
" I didnt deserve to get this kinda beating"
He cut the inside of his mouth, he was fine just fatigued and looking for a way out because he hasn't the mentality & knew Lopez wasn't going anywhere.
