Maybe this will teach him to get into real shape from now on. If your carrying too much weight of course your joints are going to be under more strain than they should be and that is exactly what happened here. I must say I think the punch did stun him a bit though but I was never that confident in his chin anyway. Haye seriously hurt him with one shot when he was a skinny little amateur and was wearing big gloves and a head guard and Solis was in shape in those days!
