The Canadiens delivered some bad news to their fans Monday afternoon with the announcement that Alex Galchenyuk is out indefinitely.

“Alex Galchenyuk suffered a lower body injury on December 4 in Los Angeles,” the team announced in a statement. “He went for medical testing in St. Louis earlier today, and will be out indefinitely. He will be further evaluated by team doctors in Montreal on Wednesday. An update will be released later this week.”

Galchenyuk was involved in a knee-on-knee collision with the Kings’ Anze Kopitar during the third period of the Canadiens’ 5-4 shootout win Sunday afternoon in Los Angeles. Galchenyuk’s right knee collided with Kopitar’s right knee. Galchenyuk tore the anterior-cruciate ligament in his left knee during a preseason game with the junior Sarnia Sting in September 2011. Galchenyuk was limited to two regular-season and six playoff games that season as a result of the injury, but the Canadiens still selected him with the No. 3 pick at the 2012 NHL Draft. The 22-year-old is leading the Canadiens in scoring this season with 9-14-23 totals in 25 games and ranked 13th in the NHL scoring race through Sunday’s games.

Galchenyuk has played in 130 consecutive games, dating back to Feb. 21, 2015 when he missed a game against the Columbus Blue Jackets with the flu . The only Canadiens player with a longer current iron-man streak is Tomas Plekanec, who has played in 195 consecutive games, dating back to March 29, 2014.
