BOSTON, Aug. 20 (UPI) -- Boston Red Sox outfielder Carl Crawford will have elbow surgery and miss the rest of the season, the team announced Monday.

Crawford, who signed a seven-year, $142 million contract with the Red Sox before the 2011 season, has already missed most of the current campaign following off-season wrist surgery.

He made his first appearance July 16, hitting .282 with 10 doubles, three homers, 19 RBI and five stolen bases in31 games.

Crawford will undergo an elbow ligament replacement procedure Thursday, to be performed by "Tommy John" surgery specialist James Andrews, the Red Sox said.

"Carl Crawford has a chronic left elbow ulnar collateral ligament tear," a team statement said. "While he has been following a conservative treatment protocol and playing with this injury, his symptoms are getting worse."
