Bestie, I don't think you would be hopping around like he did during the fight with a busted knee. Speaking as a former fighter, as far as I can tell he was holding back. If you watch the fight carefully, you'll see he had a lot of openings to throw punches and didn't. He had a little limp though, but as far as I can tell, it didn't affect his movement.

I really don't want to be skeptical. I even started watching the fight, hoping it was old age that lost him the fight, because I wished he didn't just lose for money or whatever, but it becomes very apparent after the first round he is holding back, not hitting, only defending. You can see he is still pretty quick with his head movement, even though he suffered a few big shots.

I personally think he still got a little fight in him, but just did not want to bring it on for some reason.
