WASHINGTON — Sidney Crosby has been diagnosed with a concussion and will miss at least Game 4 of the Eastern Conference semifinal series between the Capitals and Penguins, Pittsburgh coach Mike Sullivan announced Tuesday.
Crosby sustained the concussion after a crosscheck from Capitals defenseman Matt Niskanen 5 minutes and 24 seconds into the first period of Game 3 on Monday, which the Caps won 3-2 in overtime to bring the series to 2-1, Pittsburgh’s favor.
Niskanen was assessed a five-minute major and a game misconduct for the hit on Crosby, but will not receive further punishment, as he won’t have a hearing with the NHL’s Department of Player Safety.
Sullivan also announced forward Conor Sheary sustained a concussion after colliding with teammate Patric Hornqvist in the second period. Neither Sheary nor Crosby returned to the game, though Sheary did skate Tuesday morning.
Crosby has a documented history of concussions. He missed the first six games of the 2016-17 season with a concussion sustained in the preseason and also missed 101 regular season games between the 2010-11 and 2011-12 seasons with concussion-related issues.
Game 4 will be played at PPG Paints Arena in Pittsburgh on Wednesday. Puck drops at 7:30 p.m.
