Already without Evgeni Malkin, Pittsburgh's road to home-ice advantage in the first round of the playoffs just became even tougher.

Penguins goaltender Marc-Andre Fleury has suffered a concussion and will not be available for Saturday's game against the New York Islanders, the team announced.

There is no timetable for his return, according to Dave Molinari of the Pittsburgh Post-Gazette. An update on his condition is expected Monday.

"Marc wasn't feeling well when he came to the rink (Friday) and we sent him to see our doctors," said head coach Mike Sullivan. "He was diagnosed with a concussion (Friday) afternoon, so he's not with us right now."

The 31-year-old most recently played in Thursday's 5-2 win over the Nashville Predators. It's the second concussion of the season for the netminder after he missed two weeks of action in December with another head injury. Since returning in the new year, he has been one of the league's top goaltenders.

Matt Murray will take the reins in net for the foreseeable future. The 21-year-old rookie has a 5-2-1 record in eight starts so far this season. Jeff Zatkoff will serve as his backup.
