Saturday's game between Philadelphia and the New Jersey Devils was suspended early after Flyers goaltender Michal Neuvirth collapsed in net.
Neuvirth went down without any contact.
Neuvirth, 29, had made six saves while on the ice for the first seven minutes, 37 seconds.
He was taken off the ice on a stretcher and replaced in net by Anthony Stolarz. Neuvirth was conscious on the ice.
The Flyers, who scored the first two goals of the game, did not have an immediate update on Neuvirth.
