Washington, DC (SportsNetwork.com) - Philadelphia Flyers goaltender Steve Mason left Sunday's game against the Washington Capitals with an undisclosed injury.

Mason was near the Flyers bench during a break with around 8 1/2 minutes left in the second period, and eventually came off the ice and had to be helped into the locker room by trainers.

Ray Emery replaced Mason, who had made eight saves up to that point.

Mason was sidelined two weeks in January with a lower-body injury. He entered Sunday's game with an 11-12-7 record and a 2.30 goals-against average this season.

Philadelphia general manager Ron Hextall said after the game that Mason will be evaluated on Monday to determine the extent of the injury, but did rule him out from traveling with the team for Tuesday's game in Montreal.
