what? He did return and played some games last season. He wasn't particularly a good player and it probably wasn't his future so I don't know what happened since, but he definitely returned.
These athletes are insane and players with worse injuries recovered in the past. He may not be the same, but I don't think this will force him to retire. Out for season for sure tho. Didn't Kevin Ware with same injury comeback after 6 months?
