PITTSBURGH -- Evgeni Nabokov started on consecutive nights for the first time this season, and it also was his sixth straight start. Jack Capuano had to go to Kevin Poulin, called up from Bridgeport to replace Rick DiPietro, for the third period of Sunday night's 6-1 loss to the Penguins.

"As I told Kevin on the plane coming here, we have no reservations about putting him in there," Capuano said Sunday morning. "We've got three days' rest coming up and Nabby has been playing really well."

Poulin allowed one goal in his first appearance since Feb. 24, when he started and lost, 4-2, to Carolina. He's likely to get one of the two games in Florida this week.

Defense a bit banged up

Despite the defense being a bit worn down, the Isles stayed with the same six and sat Joe Finley for a second straight game.

Lubomir Visnovsky played 21:20 Saturday in his return from a two-game excused absence to be home in Slovakia, but he was ready to face the Penguins.

Andrew MacDonald recovered from a wild third period Saturday to play Sunday night. He blocked a shot by Alex Ovechkin that cracked the boot on his right skate, then took a stick to the chin that required seven stitches on his next shift.

Malkin out for Pens

Evgeni Malkin will be out one to two weeks with an upper-body injury suffered in Saturday's 5-4 shootout win in Toronto. Penguins coach Dan Bylsma said he did not think Malkin suffered a concussion when he tried to duck under a clean hit by James van Riemsdyk late in the third period and instead got the full force of the hit to his shoulders and head. Malkin sat out overtime and the shootout.
