Hamlin has not decided on off-season surgery:

From #11-Denny Hamlins media availability Friday at Martinsville: Q: Have you made any decision about surgery in the off-season? Hamlin: ‘As far as surgery, I still havent decided on it. I still havent met with the doctors to figure out the best option. I have been feeling so much better this last month or so that Id like to steer away from surgery if possible. Obviously, I dont want to just cover up the pain with the treatments that Ive been doing. That just numbs you a little bit. We still have an issue there that we have to address in the next month or so.”(Toyota Racing PR)
