"Right when you think you're taking steps to get healthier, we take two steps back," Lightning coach Jon Cooper said Thursday. "Point was really coming into his own."
Point, Tampa Bay's third-round pick (No. 79) in the 2014 NHL Draft, has 15 points (three goals, 12 assists) in 36 games this season, including a goal and three assists in his past five games.
Forward Vladislav Namestnikov , who also left the game against the Canadiens with an upper-body injury, is day to day.
The Lightning host the Toronto Maple Leafs on Thursday (7:30 p.m. ET; TVA Sports, SUN, SNO, NHL.TV).
