He may need more surgery, waiting on a specialist to determine.
He isn't medically cleared to spar, hasn't been in two years and we know why; his knees are totally gone. He shouldn't be allowed to fight against.
Last I heard he was seeing a psychologist to get over the loss. Was also waiting for the medical results to make a final decision... which at the time he was going to get within a week, and it has been months now. I think his pride is still too big regardless of the results.
I just recently read that Martinez's knees weren't too good. He wants to fight, but if he needs surgery again he'll retire for sure.
That's the last I heard, too.
After what Cotto did to him I doubt he will ever fight again. He was not a very good middleweight champion and he seldom fought the best challengers. He was looking for a big payday with a smaller man when he fought Cotto but it backfired on him. He was never going to fight GGG so I don't respect as a good champion. He was a good fighter but not a good champion because good champions fight their top challengers and Martinez refused to fight GGG.
