If he's safe and cleared to wrestle by a good doctor then let him come back and wrestle now if he wants to. They could really do with him. Many ways they could go. But he has a fan base and interest in him, he could help have some excellent feuds and matches. Bryan vs AJ, Rollins when he returns, Taker, and a bunch of others could be interesting. Against Samoa Joe too, he's a good worker, I think he should work a limited schedule though and also go back to a more intense submission/ground/aggressive style rather than too highflying. He can save that for the big shows, he should alter his style a little to try prevent injury.
