According to the team, Perreault needed the assistance of the team's training staff to leave the ice with just under 10 seconds remaining in the second period, after sustaining a cross check from Chicago left wing Daniel Carcillo. Carcillo received a minor penalty for cross-checking.
The Jets Twitter account announced several minutes after the penalty was issued that Perreault would not return to the ice.
Perreault, a 27-year-old with six years in the league, has 15 goals and 29 points in 44 games this year with the Jets. He joined Winnipeg this year after a one-year stint with the Anaheim Ducks and four years with the Washington Capitals.
Carcillo, 29, known as a fighter, has amassed 1,209 penalty minutes in his career. In his first two full seasons, he led the league in penalty minutes. He was suspended 10 games for shoving a linesman during the playoffs two years ago, but had the punishment reduced to six games.
Winnipeg defeated the Blackhawks 4-2 to move to 24-15-8. The Jets face the Coyotes at home on Sunday at 7 pm EST, while Chicago (28-14-2) hosts the Dallas Stars on Sunday at 6 pm EST.
