St. Louis Blues forward Steve Ott is set to miss three months after undergoing right hamstring surgery on Tuesday.

The surgery successfully re-attached and repaired his hamstring, which he injured in Saturday's 4-1 loss to the Toronto Maple Leafs.

The team placed Ott on injured reserve Sunday, ahead of the surgery.

The 33-year-old has played in 21 games for the Blues this season, registering two assists and 34 penalty minutes.
