Henri Jokiharju is out week to week for the Sabres because of a lower-body injury, coach Don Granato said.
The defenseman, who was placed on injured reserve, sustained the injury in a 4-3 overtime loss to the Pittsburgh Penguins on Friday, when he had two shots on goal, one hit and one block in 23:59 of ice time.
Jokiharju has four points (one goal, three assists) in 16 games, missing 11 games earlier in the season because of a facial fracture.
Forward Vinnie Hinostroza, who has not played since Nov. 30, was also placed on injured reserve because of an undisclosed injury.
Defenseman Kale Clague and forward Brett Murray were each recalled from Rochester of the American Hockey League. -- Wes Crosby
