Ehlers needed help to get off the ice after he got hurt with 5:34 left and went straight to the locker room in the Jets' 5-4 shootout win.
Winnipeg coach Scott Arniel said after the match that the team will know more about Ehlers after getting home. The Jets will pay host to the Edmonton Oilers on Sunday night.
Arniel said it was “just a little bit of the injury that he had before.” The 29-year-old Ehlers missed nine games with a lower-body injury before returning on Dec. 18 at Anaheim.
“They just ran into each other. It was a tough play, especially to lose him on that situation,” Arniel said. “It wasn't a blocked shot. ... It was a freak accident.”
“Just a weird play and a fluky play and hopefully he's OK,” Jets defenseman Josh Morrisey said.
Shold Ehlers be out for an extended period, it would be a big blow for Winnipeg (55-21-4), who clinched the franchise’s first Central Division title and the No. 1 seed for the Western Conference playoffs on Saturday night.
The 29-year-old Ehlers has 24 goals and 39 assists in 69 games.
