Calgary Flames forward Matthew Tkachuk suffered a concussion during the team's first-round series against the Dallas Stars, general manager Brad Treliving said on Monday, according to Postmedia's Wes Gilbertson.

The concussion forced the star out of the team's final four postseason games.

The 22-year-old left Game 2 of the series after getting sandwiched between two Dallas players. He managed one goal and one assist in six playoff games prior to his departure.

Treliving also said two other key players suffered significant injuries during the club's qualifying-round series against the Winnipeg Jets. Defenseman Rasmus Andersson played through a broken foot, and forward Sam Bennett played with a torn tricep muscle.

Bennett was a vital piece for the Flames during the postseason, racking up five goals and three assists over 10 games. Andersson was equally important, recording three goals and two assists in five contests while averaging 21:27 minutes of ice time.
