Kane's injured reserve status, according to TSN's Ryan Rishaug, is retroactive to Feb. 2. The left-winger missed Winnipeg's most recent game against the Vancouver Canucks on Tuesday after an incident with teammates.
The 23-year-old's status with the team has been complicated this season by concern over an injury that could require season ending surgery. The team's report did not mention any potential medical treatment for Kane.
Kane, in his sixth year in the league, has appeared in 37 games this year. He has scored 10 goals and earned 22 points.
The Jets, who have a 26-18-9 record so far this season, have lost their last five games. Their next game is against Chicago at home on Friday at 8 p.m. ET.
