Rangers President and General Manager Glen Sather announced today that forward Sean Avery suffered a lacerated spleen in Tuesday night’s game, and will be sidelined for the remainder of the season.

He was taken to St. Vincent’s hospital after the game, and was admitted following a CT scan.  He is expected to make a full recovery during the off-season.
