He's stating he's coming back by the end of the year, I'm thinking possibly at 140. He hasnt fought in over 2 years, don't think he'd be a major player at 140 imo but he will make for fun fights. MAYBE.
His style wasn't really the type that simply sitting out will rejuvenate him. It's a get all you can out of it for as long as you can. Then being permanently likely affected, that took some years off. I don't think it'll end well at the higher level for him
