Pacioretty hurt his arm midway through the first period of Montreal's season opener against the Toronto Maple Leafs when he was hit along the boards by Colton Orr. Pacioretty missed the rest of the first period and the first few shifts of the second before coming back to finish the game.
Pacioretty participated in Montreal's practice Friday, but said afterward that he couldn't guarantee he would be able to play in Saturday's game. Coach Michel Therrien said Saturday after the team's morning skate that he considered it "too risky" to put Pacioretty in the lineup.
Pacioretty's absence, coupled with that of George Parros (concussion), ensures that rookie Michael Bournival will make his NHL debut while Ryan White will make his season debut after both sat out Tuesday's game.
