Edmonton Oilers forward Alex Chiasson bumped into Price during the first period of Monday's game, and Jake Allen replaced the Canadiens starter to begin the second period. Ducharme confirmed postgame that Price's injury occurred on the play in question.
Montreal is scheduled to play four times before next Tuesday. The Canadiens will play a road contest against the Oilers on Wednesday before facing the Flames in Calgary on Friday, Saturday, and Monday to wrap up a five-game trip.
Chiasson wasn't penalized for Monday's incident.
Price was in his second game back after missing six due to a lower-body injury. The 33-year-old has a .901 save percentage through 25 games this season while also posting minus-5.63 goals saved above average and minus-8.11 goals saved above expected in 2021, according to Evolving Hockey.
