Hopefully some genuine time off from the game maybe could finally allow him to heal.
Judging by the comments he's made on social media, still suffering months on from his knock you would have thought he's already being advised to pack in the game and move on with a new career which is as people have said a crying shame for someone with such potential.
The only saving grace is I suppose he has a number of off field interests that he can diversify into.
