Baltimore Orioles catcher Matt Wieters, who was an All-Star in 2011 and 2012, will undergo Tommy John surgery on Tuesday to repair his torn ulnar-collateral ligament, the team announced.

The recovery time from that procedure is shorter for a position player than it is for a pitcher. Nonetheless, Wieters is expected to be sidelined for nine months, and will miss the rest of the season.

If there are no setbacks, he should be ready to return for the start of the 2015 season.

Wieters has been bothered by the shoulder injury for several weeks. He was hoping to return to action in early July, but when he was unable to make progress, he visited Dr. James Andrews again. It was determined the surgery was necessary.

Wieters played in just 26 games this season, hitting .308 with five homers and 15 RBIs. The Orioles were 16-10 in games he started and 17-23 without him.

Caleb Joseph and Nick Hundley are expected to be the Orioles' catchers in Wieters' absence.
