I don't think he will fight again his body is past it and he needed almost a year off after the Chavez jr fight and looked pretty poor against Murray. Maybe he'll come back for one big pay day against golovkin in a year or so if hbo have hyped him and he's continued to win but I wouldn't be that surprised if he never fought again.
Didn't Martinez break his hand against Murray? If so would explain why he's taking the rest of the year off.
There goes the Chavez Jr rematch down the toilet as I cannot see the Mexican being able to make MW in a years time. We'll see where GGG is placed when he returns.
Sounds like one of these tactics to duck opponents, a bit like Floyd's fake retirements post Hatton. Martinez should either retire or have one big fight and then call it a day.
