Flyers goalie Steve Mason is out at least for the weekend after suffering an upper body injury today in practice.

General manager Ron Hextall released this update: "Steve Mason has an upper body injury and is out for the weekend. We wil have an update on Monday".

The Flyers play at Toronto on Saturday and Winnipeg on Sunday.

The Flyers were nearing the end of practice at the Skate Zone. After practice the Flyers departed for Toronto and Saturday's game with the Maple Leafs.

Mason didn't travel with the Flyers on Friday.

The speculation is that the upper body injury is his back.

"It is what it looked like," forward R.J. Umberger said about Mason's back. "He grabbed something behind him and reached for the puck.

"I didn't see a whole lot and don't know exactly what happened to be honest with you," Berube said. "I was watching the guys with the drill we were doing and I looked over and Mason is kind of on his stomach. From there I didn't see what happened."

"It is tough to see your starting goalie and the guy who kind of held this team together when we weren't playing well and it's tough to see him go down like this," forward Matt Read said.
