Faulk, who leads the Hurricanes in scoring with 34 points, left practice Thursday after getting tangled with forward Brad Malone and falling hard into the boards. Faulk was on the ice prior to Carolina's morning skate Friday, but did not continue to skate with the group.
"He got treatment this morning, and he will be a game-time decision," Hurricanes coach Bill Peters said. "I think he will be able to play, but we'll see."
Penguins coach Mike Sullivan confirmed defenseman Trevor Daley will play, after he left a 3-0 loss Wednesday to the New York Rangers in the first period and didn't return.
"He felt pretty good out there today," Sullivan said after the morning skate.
The Hurricanes are coming off a four-day break that followed a 1-1-1 road trip. With the New York Islanders following on Saturday at PNC Arena, Carolina knows the significance of facing two teams they are chasing in the Eastern Conference.
"You look at the standing every night, and people are picking up points," said forward Jeff Skinner, who leads the Hurricanes with 19 goals. "If you're not getting points, you're falling behind. So it's big for us to come out this weekend and have a big two games. You're playing for the two points, but also so the other team doesn't get the two points."
The Hurricanes won the first two games against the Penguins this season, 2-1 on Dec. 19 at Pittsburgh and 3-2 on Jan. 17 in Raleigh. The Penguins won 5-0 at home on Jan. 17. Penguins captain Sidney Crosby expects the fourth game to be competitive.
"I think we play pretty similar games, to be honest with you," said Crosby, whose seven-game goal-scoring streak ended in the 3-0 loss to the Rangers. "We're both pretty fast-paced. When we've played one another, the games have been quick up and down the ice, so I expect that style of game here."
