Philadelphia, PA (SportsNetwork.com) - Philadelphia Flyers goaltender Steve Mason left Saturday's start against the Boston Bruins with a right leg injury.

Just over seven minutes into the first period, Mason made a save on a Craig Cunningham shot and grabbed his right leg.

He was eventually helped into the locker room and replaced in net by Ray Emery.

The Flyers stated that he was a lower-body injury and that he will be further evaluated on Sunday.

Mason had left a practice on Wednesday and underwent an MRI to take a look at an unspecified injury, but the results were negative and he was in net for Thursday's victory over the Washington Capitals.

The 26-year-old had missed four games in December with a back injury.
