TORONTO (AP) - Mike Weir's season has ended because of elbow surgery.

The Canadian left-hander underwent surgery to repair a torn tendon in his right elbow on Thursday. With a recover period of three to six months, he's not expected back on the PGA Tour until 2012.

His 2010 season also was cut short by a torn ligament in his right elbow. He hasn't played since withdrawing from last month's RBC Canadian Open.

He made just two cuts in 15 PGA events this year and earned $23,312. He managed to break 70 in one of the 34 rounds he completed.

The former Masters champion has fallen to 539th in the world rankings.
