All-Star Bo Horvat will lose one of his linemates.
"Losing a guy like him is going to be tough for us," Horvat said, according to The Province. "He was a huge part of our team and had a pretty impressive year. It just shows his character. It [the wrist] has been pretty much been bugging him all year -- and even for the last couple of years -- and for him to play through that is impressive."
Granlund had 10 shot attempts on Saturday.
"I talked to him after the [Edmonton] game and said: 'At least you went down swinging.' He had all those shot attempts trying to get his 20th goal and you can't ask for anything more than that," Horvat said.
"He's a professional. His play speaks for itself and his improvement this year has been second to none, and it's been awesome to see."
