The Vegas Golden Knights placed goaltender Marc-Andre Fleury and forward Jonathan Marchessault on injured reserve Sunday, general manager George McPhee announced.

Fleury took a knee to the head in Friday's loss to the Red Wings. The NHL didn't think the hit was severe enough to take him off the ice as part of its concussion protocol, but Fleury has a history of concussions.

Marchessault suffered a lower-body injury Friday. Both players are expected to miss at least a week.
