PITTSBURGH -- Sidney Crosby sustained a lower-body injury early in the third period of a 3-2 shootout win for the Pittsburgh Penguins against the Chicago Blackhawks at PPG Paints Arena on Saturday.
The center did not return after blocking a shot from Erik Gustafsson at 1:43 of the third. Coach Mike Sullivan said he expects to have more information after the Penguins practice Monday.
Pittsburgh already is without defenseman Kris Letang and forward Patric Hornqvist , each out with a lower-body injury. Letang is week to week, and Hornqvist is out longer term.

"You certainly find out about your depth out of necessity," Sullivan said. "I think guys have stepped up that we've put in the lineup. They've done a terrific job."
Jake Guentzel and Bryan Rust scored, Evgeni Malkin had two assists, and Matt Murray made 29 saves for Pittsburgh (10-6-1), which was 0-7-3 in its previous 10 games against Chicago since a 4-1 home win March 30, 2014.

Dominik Kubalik and Patrick Kane scored, and Corey Crawford made 29 saves for the Blackhawks (5-7-4), who have lost four of their past six games (2-2-2).
"Pretty good performance, overall," Chicago coach Jeremy Colliton said. "Disappointing to not get two points because I thought we were in pretty good shape, playing well and with a lead. ... We had our chances. I think we had more than enough opportunities to end it, but disappointed in that. I liked our effort. I thought we competed really hard."
Guentzel and Jared McCann scored in the shootout for the Penguins. Kane scored in the second round, but Murray made the save on Jonathan Toews and Alex DeBrincat.
Kubalik put the Blackhawks ahead 1-0 at 7:09 of the second period. The rookie forward dropped to one knee for a one-timer by Murray's glove at the end of a 3-on-1.
Kane made it 2-0 on a snap shot from the right face-off circle at 8:47. He has eight points (three goals, five assists) during a five-game point streak.

Guentzel cut it to 2-1 at 16:04. Malkin held off Slater Koekkoek while carrying the puck into the near corner on a 2-on-1 before passing out front to Guentzel for a one-timer.
Rust scored on a sharp-angled shot, tying it 2-2 at 10:57 of the third period. He has seven points (five goals, two assists) during an NHL career-high six-game point streak.
"Just trying to work hard," Rust said. "Individually, just trying to move my feet. Trying to get to open spaces and make plays when they're there. Been having really good fortune of some really good play from my linemates.
"I guess things feel good but I might know better than anyone else that things can just as quickly [turn] for the bad as for the good. Just have to keep plugging away here."

They said it
"Would've been nice to come away with that game but they're a good team. They've been playing well all year. They had a big comeback against the [New York] Islanders the other night. Obviously, nice to get a point. Hopefully keep building on what we have going on here, but it would've been nice to have two." -- Blackhawks forward Patrick Kane
"Obviously, [Crosby is] the best player in the world, so if he's out it's going to take a committee by everyone to step up. We'll have to see what happens." -- Penguins forward Jake Guentzel
