Pulock (upper body) has been ruled out of Saturday's tilt versus Buffalo, Stefen Rosner of NHL.com reports.
Pulock left Wednesday's game versus the Kraken in the third period and did not return. He has two goals, 21 points and 93 blocked shots in 50 appearances this season. The Islanders recalled Isaiah George from AHL Bridgeport on Saturday, and he will take Pulock's place in the lineup.
