The Flyers, 3-6-2 in their past 11 games, have allowed at least four goals against in six of their past nine games.
The Flames, 5-1-0 in their past six games and 9-2-1 in their past 12, have allowed two goals or fewer in seven of their past nine games. Calgary is in first place in the Pacific Division, three points ahead of the San Jose Sharks.
