PITTSBURGH (AP) — The status of Pittsburgh Penguins captain Sidney Crosby for Wednesday's Game 4 of the playoff series against Washington is uncertain.

The NHL's leading scorer left Game 3 after taking a hit to the head from Capitals defenseman Matt Niskanen. Penguins coach Mike Sullivan said Crosby will be evaluated today.

The Penguins were in Washington's end of the ice when Niskanen crosschecked Crosby across the face with his stick. Crosby was skating by Washington goaltender Braden Holtby when he turned and faced Niskanen.

Niskanen raised his stick and hit Crosby flush. Crosby was on the ice in obvious pain for several minutes before leaving the ice slowly under his own power.
