Danault was struck by a shot from teammate Tomas Tatar early in the second period of a home game against the Arizona Coyotes and had to leave the game.
Canadiens head coach Claude Julien added that Danault will likely wear a full face mask.
This isn’t the first time Danault has been injured by a puck to the face. In 2018, he missed over a month after taking a slap shot from Zdeno Chara to the head. In that instance, he was diagnosed with a concussion.
Danault is a reliable centre who plays in all situations for the Canadiens. The 26-year-old has 12 goals and 40 points in 58 games, and is second on the team with a 54-per-cent success rate on faceoffs.
In other Canadiens news, Julien said winger Paul Byron will travel with the team too. Byron has been out of the lineup since mid-November with a knee injury.
