Rask suffers another concussion
"He's concussed," Cassidy told reporters, including the Boston Herald's Marisa Ingemi. "He got elbowed in the head. He'll probably go to protocol. At least that's what I was told; maybe it’s not as bad as first thought. I guess we'll have a better evaluation (Wednesday)."
"It's an elbow to the head is what it is, it's a penalty," the Bruins bench boss added. "But they missed it, you move on. It's just unfortunate it happens to your No. 1 (goalie). It was pretty clear to me."
Here's another angle:
Bemstrom hit Rask just over a minute into the game and - as Cassidy mentioned - wasn't penalized.
