The Flyers on Wednesday afternoon assigned defenseman Samuel Morin to the Lehigh Valley Phantoms, officially securing Travis Sanheim's spot on the NHL roster.

Morin served as a healthy scratch during the Flyers' four-game season-opening road trip. The Flyers carried eight defensemen out west because of an upper-body injury to Shayne Gostisbehere, but the third-year defenseman didn't miss a game.

"It's the first time in my career that I've been a healthy scratch and it's pretty hard," Morin said Tuesday in Nashville. "What else can I do? I think it's normal that I'm pretty upset. I just need to keep working hard and see what's going to happen.

"There's not much I can do right now. … I'm sure I can play in this league. If I go back to the AHL, I'm going to just work my ass off like I do all the time. I just want to play in the NHL, honestly."

After their preseason finale, Flyers general manager Ron Hextall said defenseman Robert Hagg and center Nolan Patrick earned their spots but didn't say who won the competition for the second opening on defense.
