The Pittsburgh Penguins came up on the short end of their Stadium Series meeting with the Philadelphia Flyers on Saturday night, but it appears the club suffered a pair of much more significant losses during the overtime affair.
Top-pairing defencemen Kris Letang and Brian Dumoulin were both knocked out of the lineup with injuries early during the game. According to head coach Mike Sullivan, Dumoulin has been diagnosed with a concussion, while Letang is being evaluated for an upper-body injury.
The Penguins were forced to play the majority of the night with only four available blueliners, as Letang and Dumoulin finished the game with just 6:18 and 6:06 minutes of ice-time, respectively.
Pittsburgh is also currently without mainstay defender Olli Maatta, who was placed on injured reserve earlier this month.
