This would not be a good idea for his career. When a shoulder fully dislocates as his did, the ligament stretches and the muscles around the shoulder tear. Sure the pain mostly subsides when it is popped back in, but it takes time to heal fully if you don't want it to become a recurring issue. Best course of action is to immobilize it in a sling for a couple weeks, then build the strength up through physio. Often it becomes a recurring issue that eventually requires surgery anyways (if you're a professional athlete), but he should rehab it fully to minimize the likelihood of that before jumping back in there.
