You can add four new names to the growing list of NHL players out with concussions.
New York Islanders goalie Al Montoya and forward David Ullstrom were injured against the Winnipeg Jets while Jesse Winchester of the Ottawa Senators and Marcus Kruger of the Chicago Blackhawks suffered the same fate in their respective games on Tuesday night.
Montoya was knocked out of his game late in the second period after a collision with Jets forward Evander Kane, who was given a penalty for goaltender interference despite arguing that defenceman Milan Jurcina pushed him into the goalie.
Ullstrom left the same game in the overtime period after crashing back-first into the boards.
Early in the first period in Ottawa, Jesse Winchester suffered a concussion after he was hit into the boards by Buffalo Sabres forward Paul Gaustad. No penalty was called on the play.
Also in the first period in Pittsburgh, Penguins defenceman Deryk Engelland led with his forearm in delivering a hit to Marcus Kruger's head. Kruger played the remainder of the period but didn't play after that. Engelland was not penalized for the hit. Engelland has been informed he will have a hearing with the league office but it has not been scheduled as yet.
The list of players sidelined with concussions is now over 30, including Sidney Crosby, Chris Pronger and Kris Letang.
