Yeah, he's probably done after that one. I'm a huge fan of Silva, but he has gotten a bit cocky in his fights (probably the biggest reason he has started to lose more and more). That sucks though and I hope he has a speedy recovery.
Kevin Ware is a bad example, he is a lot younger than Silva. He is a cool dude, though. Chatted with him a bit one night at my apartment building on campus. We were playing pool with a couple of the basketball players. Fun stuff!
