The Flyers lost two players during the first period of their game against the Washington Capitals in Carter Hart and Cam Atkinson.
The former seemed to be bothered with his right leg. As a reminder, he was dealing with a nagging injury for quite some time and and it may have gotten worse.
In the case of Cam Atkinson, he was hit hard from behind by forward Tom Wilson. He went straight to the locker room after this.
