Ottawa Senators forward Bobby Ryan left Tuesday's game against the Buffalo Sabres in the first period with a hand injury.
Following the game, Senators head coach Guy Boucher said Ryan would miss some time with the injury.
Ryan, 29, also left Nov. 17's contest against the Nashville Predators when he blocked a shot in the opening period. The injury caused him to miss two games.
Ryan has three goals and five assists over 20 games with the Sens this season, his fourth with the club.
