PHILADELPHIA -- The Philadelphia Flyers' blue line is suddenly in need of reinforcements.
Shayne Gostisbehere, who leads all NHL defensemen with 13 points in 11 games, is questionable for Monday night's game against the winless Arizona Coyotes with an upper-body injury.
Gostisbehere, who ranks second behind Ivan Provorov in average ice time (21 minutes, 8 seconds), was checked from behind into the glass by Toronto Maple Leafs forward Leo Komarov in the second period of Flyers' 4-2 win on Saturday night. He played one more shift after the hit, which was not penalized, and did not return for the third period.
