Pittsburgh Penguins goaltender Marc-Andre Fleury is set to miss at least one-to-two weeks after suffering a concussion.

Fleury may have suffered the concussion in Penguins' 4-1 loss to the Washington Capitals on Monday night.

Penguins general manager Jim Rutherford confirmed Fleury's injury, but said he there was no concrete timetable.

“I haven’t talked to the doctor yet. I don’t have any further information other than he was examined, and it was determined he was concussed,” Rutherford told the Pittsburgh Post-Gazette. “At a minimum one to two weeks. You can’t put a timeline on these things though.”

Penguins coach Mike Sullivan said Fleury told the team he was feeling symptoms after the team's Tuesday morning practice.

“Marc came to us after the game and said he did not feel right and so, potentially it’s a concussion,” Sullivan said prior to Rutherford's announcement.

Sullivan added Fleury did not mention when he believed he could have sustained the injury, but that he believes it did not occur during Monday's loss.

Fleury is 13-10-2 on the season with a 2.29 GAA and a .925 save percentage. The Penguins are 15-11-3 on the season and sit fifth in the Metropolitan Division.

Forward Beau Bennett suffered an upper-body injury in the loss has been ruled out for four-to-six weeks.

Bennett, 24, has five goals and 10 points in 24 this season. He sustained his injury in the first period against Washington after being checked by Capitals forward T.J. Oshie. He left the ice immediately and did not return.
