Mike Weir underwent right elbow surgery on Thursday and will be out of action for three to six months to rehab.

Weir battled elbow injuries through much of last year, but the Canadian star finally went under the knife on Thursday.

The renowned Dr. James Andrews performed the procedure at his Pensacola, Fla. office and it was deemed a successful surgery to repair the extensor tendon.

Weir, the 2003 Masters champion, stopped playing around this time last year after the elbow started bothering him, but he was already in the midst of a tough season. Weir made 11 of 19 cuts in 2010 and didn't post a top 10 after his first tournament of the year at the Bob Hope.

Declared ready to go, but with no status on tour, Weir played the 2011 season under a major medical extension and with sponsor's invites, but his struggles continued. He made only two cuts in 15 starts and his best finish was a tie for 70th at the AT&T National.

After hitting a shot from the rough at the Canadian Open, Weir withdrew and almost a month later, his season is over.

"My elbow has caused me problems over the past year and during the RBC Canadian Open it essentially became unplayable," Weir said in a press statement. "Dr. Andrews is the best in the business, and it's my hope with patience, and diligent post-surgery rehab, I will be able to put my elbow problems behind me and look forward."
