Kevin Hayes scored after he lost a goal because of an offsides challenge, and the Flyers beat the Chicago Blackhawks 4-1 on Thursday night.

Claude Giroux, James van Riemsdyk and Oskar Lindblom also scored for Philadelphia, which beat Chicago 4-3 in Prague in the season opener on Oct. 4. Brian Elliott made 23 saves in the Flyers' first win in their fourth road game.

It looked as if Hayes scored the first goal 6:09 into the first, but the Blackhawks challenged the play and the call was overturned because Hayes was offsides. Joel Farabee's first career goal was thrown out in the third because of another offsides challenge.

But there was no disputing Hayes' breakaway 5:03 into the final period. He skated away from Chicago defenseman Brent Seabrook and beat Robin Lehner for his third of the season and a 3-1 lead.

The Blackhawks closed out a disappointing 2-3-2 homestand with their third consecutive loss. They had just one shot on goal in the second, and the crowd of 21,315 booed during the final seconds of the period.

Brandon Saad scored for Chicago early in the third, and Lehner finished with 19 stops in his second straight start.

The Blackhawks visit the Carolina Hurricanes on Saturday.
