Toronto Maple Leafs goaltender James Reimer is expected to miss Monday's game against the Philadelphia Flyers, according to a report by TSN.
Reimer left Saturday's game against the Montreal Canadiens with a minor neck injury. Reimer, who lost his mask on the exchange with Brian Gionta, was dazed following the collision.
He was replaced by Jonas Gustavsson, who turned aside 15 of 18 shots to lift the Maple Leafs to a 5-4 overtime victory.
Reimer did not practice on Sunday and is considered day-to-day.
"I'd be shocked if it was anything more than a couple days, but you never know," Reimer told TSN. "It is looking better because I am lot better today than I was yesterday."
