Philadelphia Flyers center Claude Giroux told reporters Friday that teammate Nicklas Grossmann has a concussion, meaning the defenseman will not be in the lineup for the team when it faces the Pittsburgh Penguins in Game 5 of their Eastern Conference Quarterfinal series (7:30 p.m. ET, NBCSN, TSN).
Flyers coach Peter Laviolette later confirmed Grossmann did not make the trip to Pittsburgh, and that rookie Erik Gustafsson will make his Stanley Cup Playoff debut.
Grossmann was hit hard twice in Game 4 on Wednesday. He was elbowed in the head by Penguins center Evgeni Malkin less than four minutes into the game, and then was rocked by forward Tyler Kennedy with 8:21 left in the period. That hit forced Grossmann to skate slowly off the ice and spend time on the bench. He returned, but played just four shifts in the second period, leaving the game for good with 9:20 remaining.
After the game, the Flyers listed Grossmann as day-to-day with an upper-body injury.
