That was a brutal KO. And will alone have lasting effects. Couple that with previous Ko's and you have a man who probably should consider calling it a day.

Abraham, though, that dude has crazy explosive power. He doesn't even use it that much, short bursts, then shells back up but it is effective as hell. If he can explode more often like that in the course of a fight, and add in the guy can still fight on with his broken chin hanging off his skull, that is a scary opponent across from you. Don't care who you are.
