This injury is dictating the end of my career, whether that's this year, next year or whatever, ... I was able to rehab it and I want to find out if I can still play. Then when I retire I won't have to look back and think I could have had another year or two. I like playing the game, so if it means working hard and getting back in shape to play one more year, I think it's worth it. I know it's worth it.
