Looking at the 2012 roster, Chris isn't on it and he's not playing spring ball. However, it doesn't mean his career is done. With the help of the SU medical staff, he's rehabbing with the hope that he can one day return to the team.
As you can see from this gruesome photo (Seriously, head's up) comparing things right after surgery to how they look today, he's in way better shape.
Chris recently posted a series of videos online outlining his rehab from last year.
