The Canadiens announced Wednesday that Gionta undergo surgery on Friday. The Montreal captain sat out Games 2 and 4 of the team's first-round playoff series against the Ottawa Senators with what was called an upper body injury.
Gionta was limited to 31 games in the 2011-12 season due to torn biceps.
Ottawa leads the best-of-seven series 3-1 with Game 5 on Thursday at Montreal.
The Canadiens did have some good news as center Lars Eller has resumed skating. He was taken from the ice on a stretcher in Game 1 with a concussion and facial injuries after an open-ice hit by Ottawa defenseman Eric Gryba, who was suspended two games. There was no immediate word on when Eller will return.
Also, goalie Carey Price is considered day-to-day with a lower body injury. Price appeared to be hurt late in the third period Tuesday night in the Senators' 3-2 overtime win, and was replaced with Peter Budaj for the extra period.
