Peter Regins season is likely over.

The Senators centre wasnt on the ice Thursday morning at Scotiabank Place after his surgically repaired left shoulder stiffened up and hes going to have to decide whether hes going to have another procedure to get it repaired.

Regin wont be in the lineup against the Florida Panthers and hes out indefinitely.

Winger Bobby Butler returns and defenceman Brian Lee will be in the lineup with the club carrying seven blueliners.

It happened during the game (Tuesday) and it stiffened up on him, said coach Paul MacLean Thursday.

I think its very frustrating for Peter. For us, hes an important player we think a lot of, but its devastating for him.

He has to make the decision whats best for him. I know (surgery) is one of the options.

Regin originally suffered the shoulder injury last February.

He had surgery, took it easy in training camp and re-injured the shoulder in October. He missed 22 games and only returned Dec. 10 against the Vancouver Canucks.

The Senators were hopeful with the arrival of centre Kyle Turris from the Phoenix Coyotes, the club would have plenty of depth down the middle.

We did enjoy the depth that Peter gave us on the third line for one game, said MacLean.

Winger Milan Michalek (concussion) was on the ice with the team for the second straight day, but didnt have any contact and wont play until after Christmas.

He is expected to suit up Tuesday against the Montreal Canadiens.
