Buffalo Sabres forward Torrey Mitchell suffered a lower body injury during the first period against the Ottawa Senators and is done for the night.
Mitchell played just over four minutes while winning one of two face-offs he took.
According to Kevin Oklobzija of the Democrat and Chronicle, Mikhail Grigorenko has already been recalled from the American Hockey League’s Rochester Americans.
Buffalo plays in Winnipeg on Tuesday.
Grigorenko, 20, has seven goals and 19 points in 27 AHL games this season.
