Mason missed Thursday's 4-1 loss to New York because of an undisclosed upper-body injury. He was hurt last Saturday against Pittsburgh, when he was knocked over and hit the back of his head on the ice. Mason and the Flyers have declined to say whether he has a concussion.
Mason took part in a goalie practice Friday at New York's Chelsea Piers and said afterward that he is feeling better than he did a few days earlier. He has set his sights on playing Sunday at Madison Square Garden.
