Pittsburgh Penguins center Sidney Crosby was injured on Monday night after receiving a cross-check to the head from Washington Capitals defenseman Matt Niskanen. He was diagnosed with a concussion and will miss at least the next game, according to head coach Mike Sullivan.

Crosby, who has had a history of concussions, skated off the ice slowly. His left leg appeared to bend in an awkward manner, as well.

The incident took place in the first period of Game 3 of their Eastern Conference semi-finals series. Crosby was cutting to the net but then had his skate incidentally clipped by the Capitals Alex Ovechkin. As Crosby was falling to the ice, Niskanen hit him in the head.

Niskanen received a five minute major for cross-checking and a game misconduct. But, according to the Washington Post, he will not be suspended.

“It was an unfortunate play. I certainly didn’t mean to hurt him,” Niskanen told reporters after the Capitals defeated Pittsburgh, 3-2 in overtime.

The Capitals trail the Penguins 2-1 in the best-of-seven series.
