Perreault was hurt midway through the second period, when he lost his balance and slid back-first into the side boards. The 28-year-old remained on the ice for a lengthy period of time before exiting.
He didn’t return to the contest.
It remains to be seen if Perreault will return to action this season. The Jets have nothing to play for — at least standings-wise — and only have 10 games remaining.
This is a tough development for Perreault, however. He was on pace to set a career-best in points (was 43, has 41 this year) and already posted a career high in games played, with 71.
