Devils winger Ilya Kovalchuk will be sidelined for at least a short period of time-- if not longer-- after suffering a right shoulder injury with 10:53 remaining in tonight's victory over the Florida Panthers.

Kovalchuk crashed hard into the end boards and did not speak with reporters after the game, but he left Prudential Center with his arm hanging at his side rather than in his coat sleeve.

"He has a shoulder injury. I don't know the details or the extent," Devils coach Pete DeBoer said. "We'll get through it. He'll obviously be out at least a short time."

DeBoer said Tim Sestito, who was hurt when cross-checked into the boards soon after Kovalchuk's injury, is not seriously hurt.

"He'll be fine," the coach said.

The Devils will certainly miss Kovalchuk if he is out for an extended period, but his absence was notable when they failed to score on the 5:00 power play after Robak cross-checked Sestito.

"At times we were gripping our sticks a little too tight," Travis Zajac said. "(Kovalchuk's) absence might have something to do with that."

David Clarkson said: "Kovy has played through a lot of things. It's scary (when he doesn't come back)."

The Devils face the Senators Monday night in Ottawa and then have a few days off in Florida befire playing back to back games against the Lightning and Panthers Friday and Saturday.
