Flyers coach Craig Berube is sure Steve Mason is ready to start in a postseason game if called upon. Mason, who had been dealing with an upper-body injury, replaced Ray Emery late in the third period of Game 3 on Tuesday. "I think the practice time he's had he's looked fine," Berube said on Wednesday. "He hasn't really been with us as a team so much, we haven't practiced a lot as a team. There's been three goalies out there. We'll see tomorrow. He's going to be on the ice with us tomorrow, and we'll go from there." Philadelphia isn't likely to reveal its starting goaltender for Game 4 until just before the contest starts.
