Question really comes down to whether he needed the surgery or not. I mean, unless a specialist in wrists tells him that he can try to rehab it, then he can push for that option over surgery. Plenty of players have tried to rehab their injuries. And plenty who have tried have ended up getting the surgery that they delayed. Always explore your options as it's your body and career.
I'm just reminded of what Nate Burleson said on Tim and Sid a couple of years ago when he said that a year after he retired, he went to get a complete physical and the doctor asked him when he suffered certain injuries. Nate told the doctor, no I never suffered that, it was something else. Doctor showed him the scans and said, no, you actually ended up with this injury. Nate said his mind was blown away. Ended up getting a few surgeries to fix a bunch of stuff. Just a shocker and a reminder that team physicians work for the team. Always consult a third party on these matters, especially if you have the ability to as an established veteran.
