The beating he took from Sonnen, messed up his head I think.He absorbed a lot of leather on the head.And it is not good for you to take so much punishment on the Head.And let me tell yu??
Vitor's punches are not light like Sonnen's were.If Vitor Lands a few good ones,then Silva maybe go to sleep.And that will probably be the end of Silva.Once a fighter gets knocked out once, his head comes in to a knock out syndrom.lol
I mean look at Chuck Liddel.Once he started kissing the Floor, then he was kissing it regularly.Once a Fighter passes the 35 years of Age, the head blows become more lithal.That is Why We see knock outs lately time after time.To the likes of Chuck Liddel.Or Matt Huge.Keith Jardine.
