Looks to be just an awkward effect of the camera angle or lighting settings. I can't imagine what kind of injury would do that or what kind of surgical remedy would leave a hand looking like that. Makes me think of a guy I saw last year who had mouth cancer and had to have his mouth operated on. He ended up resembling Kermit the Frog. He was a cool guy anyway though.
The only thing wrong is he seems to be picking at it like a meth head, that suit makes him look like a cheap car salesman too.
Im a Chavez fan but the suit comment had me laughing:haha:
after the fight with cotto pacquiao's hand was liek that nothing odd its when fighter truely punish the other fighter his hands get swollen maybe thats why mayweather wont punish his oponents even thoe he could in some fights he refuses to do it i still like thoe but if he wants to be the #1 fighte rin history he has to KO guys
Its just a strange camera angle that has created a shadow on his knuckles.
When i saw the video on youtube of him and Pac i thought he has had some surgery done. Like Hagler had after he retired.
