Former five-weight world champion Floyd Mayweather said he injured his hand during his fight with MMA fighter Aaron Chalmers.
Actually, I hurt my hand, and many people don't know that. It happened when I was punching a hook. Maybe the arm is broken. But we're not worried. I can still hit with my left hand.

Recall that the fight between Mayweather and Chalmers took place on the night of February 26 in London. Because the fight was an exhibition bout, no winner was announced after eight rounds.
