All-star San Francisco Giants closer Brian Wilson will undergo Tommy John reconstructive elbow surgery Thursday in Pensacola, Fla.

Renowned elbow specialist Dr. James Andrews will perform the surgery after doing a similar procedure on Wilson when the right-hander was in college at LSU in 2003. San Francisco team orthopedist Dr. Ken Akizuki was set to travel to Florida on Wednesday night to also help with the operation.

Andrews examined Wilson on Wednesday and confirmed the Giants' diagnosis of a torn ulnar collateral ligament that will sideline him all season.

While the timeframe can be longer than the standard 12 to 18 months following Tommy John surgery, the Giants hope Wilson is a quick healer and will be able to pitch in 2013.

The 30-year-old bearded closer led the majors with 48 saves in 2010.
