Yeah, it is. Sucks that he made it through round 2 and the fight got stopped before round 3 started though. They shouldv'e given him the option to continue.
Bottom line is that he doesnt have the explosiveness anymore and he can't bang with guys that outweigh him by 50-60lbs that have skills.
Either way, he is still the greatest of all time as long as he doesn't pull a Chuck Lidell and lose 10 times in a row.
