After just one game, the Ottawa Senators are shuffling the deck.

When the Senators stepped onto the ice this morning, a little more than 12 hours after a 5-2 season-opening loss to the New York Rangers, it was with revamped lines.

In a major shift, Mike Fisher found himself back at centre between Alex Kovalev and Nick Foligno, and Peter Regin found himself between Jonathan Cheechoo and Chris Neil. A minor shift had Chris Kelly between Shean Donovan and Jarkko Ruutu. Donovan didn't play against the Rangers.

Only one line stayed the same: Jason Spezza was still between Daniel Alfredsson and Milan Michalek.

The line shuffling was partially prompted by the absence of Ryan Shannon. He got shook up in the game against the Rangers and is thought to have a concussion. He's questionable for Tuesday's game against the Leafs.

The changes come after the Senators' miserable 5-2 loss to the New York Rangers.

Daniel Alfredsson has been Erik Karlsson's host and mentor through training camp, but the Ottawa captain said he didn't try to say anything to calm the 19-year-old defenceman before his first game in the NHL.

Alfredsson still remembers his first game. It was on Oct. 7, 1995, at the Civic Centre against the Buffalo Sabres. Alfredsson was nervous.
