I just watched the fight like 2 weeks ago and i was completely baffled that he fought on may 27th and no one on linker seemed to be talking about it. It's still weird for me to see how big he is. ...even though he's technically not that big compared to other guys.
Not trying to discredit Mirko's win but it looked like Jorge gave up pretty fast. Maybe it had something to do with his arm like you hinted at, WCC. Either way, he looked good and a win's a win so i'm glad he won.
