Crosby, Sheary diagnosed with concussions

Captain Sidney Crosby has been diagnosed with a concussion and will not play in Game 4 of the Pens' Second Round series against Washington on Wednesday night at PPG Paints Arena.

"We will evaluate him day-to-day," head coach Mike Sullivan said. "He will go through the protocols that we always put our guys through when they've been diagnosed with a concussion."
Crosby suffered the concussion on Monday night following a play five minutes into the first period. During the sequence Crosby was driving to the net when Capitals winger Alex Ovechkin's stick caught him in the head.
Ovechkin also clipped Crosby's skate, causing the Pens center to lose balance and fall toward the side of the crease. At that point Capitals defenseman Matt Niskanen collided with Crosby, again catching him in the helmet.
Crosby, who hours earlier had been named as an NHL MVP candidate for the Hart Trophy, left the game and did not return.
On the play Crosby's right leg was also caught under him as he was falling. But Sullivan said there was no lower-body injury for Crosby.
Niskanen was given a five-minute major for cross checking and a game misconduct on the play. He did not receive any further supplemental disciplinary action via the NHL Department of Player Safety.
Niskanen said he was "absolutely not" trying to injure Crosby following the game.

Winger Conor Sheary also suffered a concussion in Game 3 after colliding with teammate Patric Hornqvist.
Sheary skated Tuesday morning and wasn't ruled out of Game 4 by Sullivan, but he is also going through the concussion protocol.
"The nature of these things is that they're all very different," Sullivan said. "Sometimes they come around quickly. Other times they don't. My experience of dealing with these in the past with players is that they're day-to-day things. We rely on our medical staff to advise us the right way."
