VOORHEES - The Flyers' line combinations looked a bit off Sunday morning...because Sean Couturier wasn't among the group.

Couturier skated on his own before practice began and looked like he was in pain. The Flyers don't know if he'll practice Monday or play in the preseason game against the New York Rangers, but admit that he's "a little banged up." General manager Ron Hextall says he'll know more Monday.

The 22-year-old center took a slash to the back of his right knee, an unprotected area, in Tuesday night's preseason game against the Rangers. Veteran Jarret Stoll gave Couturier the two-handed slash while the Flyers were on the power play in the first period of the game. Couturier left the game twice, but returned to finish the contest and said he was fine after the game, that he was taken out so he could be checked out.

"I think it does (throw a wrench into things)," linemate Wayne Simmonds said of Couturier's absence. "You know what you're gonna get from Coots. When he's ready to come back, when he gets back in the lineup you know what you're gonna get. I've played with Coots for a while. This is our fifth year together and I've been on his line periodically from time to time."

In his place, Scott Laughton centered the line of R.J. Umberger and Simmonds. Here were the other lines in Sunday's practice.
