Two Years.

That's how long I'll wait before I'm convinced Tito Ortiz fought his last fight tonight.  Too many fighters don't seem to know when to quit, and I wouldn't be surprised if Ortiz is one of them.  Meanwhile an obvious question is whether Chael Sonnen will fight again.  His fight tonight was his first in three years, and it was a loss.  On the other hand the fact he lost might keep him in the game, as having your last fight be a loss is a hard result to take.
