First thing I thought was he must me a kickin' mufucka! That's an opponent I wouldn't want to face because without the whole arm you have less to attack (arm holds). Good look for him to overcome though.
No offense to anybody, but you have to be an absolute bum to lose your belt to a dude with one arm via rear naked choke..but in his defense, the dude does have most of that arm and it looked like that choke is somewhat of an advantage to the new champ.
