Grossmann was injured in Game 4 of the Flyers' Eastern Conference First Round series against the New York Rangers when he fell into the boards during a battle for the puck with the Rangers' Derick Brassard.
Grossmann had zero points in four playoff games while averaging 16:23 of ice time.
During the regular season, Grossmann had a career-best 14 points in 78 games. He missed the final two games of the regular season with an ankle injury sustained blocking a shot.
He's a special guy. Obviously we are lucky to have him. Just his talent, I'm not surprised anymore. You get to see this guy every practice, and you know what he's able to do. Obviously, it's pretty special for a guy that young to score a hat trick in playoffs, this type of a game too. Really happy for him.
