Second period: Flyers 4, Hawks 2

PHILADELPHIA -- The Chicago Blackhawks trail the Philadelphia Flyers 4-2 after two periods at the Wells Fargo Center.

The Hawks gave up a trio of goals in the middle 20 minutes over the span of 4:20. They led 1-0 and then 2-1 before the Flyers exploded. The Hawks have played poorly in their own zone as 15 different players have been on the ice for at least one goal against.

Rookie Andrew Shaw scored his first NHL goal in his first game to briefly give the Hawks a second-period lead before things imploded for the visitors. Shaw also fought in the first period.

Ray Emery played well in the first but has been inundated with shots and good scoring chances. Philadelphia is outshooting the Hawks 34-22 through 40 minutes. Jimmy Hayes has the Hawks' other goal, scored back in the opening period.
