Penguins general manager Ray Shero said via Twitter that Crosby has no signs of a concussion but they will continue to monitor him for symptoms. Shero also said Crosby's jaw was not wired shut, which could be a good sign in terms of the length of his recovery.
Crosby was injured on his first shift against the New York Islanders on Saturday when defenseman Brooks Orpik fired a slap shot that changed direction and caught Crosby just under the visor.
Crosby was down for several seconds but skated off under his own power accompanied by team training staff. He went to the Penguins locker room and did not return to the game, won by Pittsburgh 2-0 for the team's 15th straight victory.
The Penguins will also be without Paul Martin for 4-6 weeks after undergoing surgery for a broken bone in his hand.
The Penguins' next two games are Tuesday at home against the Buffalo Sabres and Wednesday on the road against the New York Rangers. The Penguins are two wins shy of tying the NHL record for consecutive wins, set by the 1992-93 Penguins.
