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.
I don't know how he does it. I don't know how he gets his body parallel with the player and pulls it through his legs like that. I know he's tried it a couple times in practice and it's never worked, so how he does it in a game, it's incredible.
