The Montreal Canadiens announced Monday that defenseman Tom Gilbert will undergo surgery on his left knee and miss the remainder of the season.
The 33-year-old left Friday's game against the Philadelphia Flyers after blocking a shot during the second period.
Gilbert had one goal, one assist, and a plus-3 rating in 45 games for the Canadiens this season.
With Gilbert heading to injured reserve, the team has recalled defenseman Victor Bartley from the AHL's St. John's IceCaps.
