Buffalo Sabres forward Ville Leino is out indefinitely after suffering a cracked rib in the first period of Wednesday's 2-1 loss to the Detroit Red Wings.
Sabres coach Ron Rolston confirmed Leino's injury following Thursday's practice.
"It happened in the first period, probably about three-to-four shifts in," Rolston said. "It was just sore and it seized up overnight, and we had it checked."
Leino, who played 12:36 in the game with no shots on goal, was limited to eight games last season due to hip and lung injuries.
Johan Larsson will move into the lineup at center, paired with Tyler Ennis and Steve Ott. He will make his Sabres debut in the team's home opener Friday night against the Ottawa Senators.
"He's going to get a good opportunity," Rolston said. "I like everything about him. His attitude, the way he works, preparation. He's a good detail player. This will give him a good opportunity to play with some good players and show us what he can do. It's a good thing. He's ready."
