Sizemore undergoes surgery on torn ACL

Dr. Douglas Freedberg, who does extensive work with several of Arizona's professional sports teams, administered the reconstructive procedure, which brought about "nothing that was alarming," according to A's head trainer Nick Paparesta.
"He'll walk in the door next year as ready as anyone else," Paparesta said.
Part of Sizemore's hamstring tendon was used to replace the damaged ligament, a common practice familiar to several surgically repaired athletes, including lefty Brett Anderson, whose hamstring tendon was transplanted to his elbow and used as a graft on top of his ulnar collateral ligament during Tommy John surgery.
The 27-year-old Sizemore, who appeared primed for a breakout season before suffering the injury within two hours of the club's first full-squad workouts in February, will remain in Arizona for a couple of weeks before visiting Freedberg on March 30 for a checkup.
When comfortable to do so, Sizemore will then make his way back to Oakland, where he will rehab under the watch of the A's. During the first six weeks of that process, the infielder will work to retain his range of motion. The next step will be strengthening the knee, in an effort to begin baseball activity again.
