Flyers defenseman Nicklas Grossmann suffered an apparent right knee injury during the second period of Friday's 2-1 win over the Rangers in Game 4 of the divisional semifinals (see Instant Replay).
Grossmann, the team's second-leading shot-blocking defenseman, left the game with assistance from the training staff less than six minutes into the period. He got tangled up with Rangers forward Derrick Brassard in the corner.
"I do not have an update right now," Flyers head coach Craig Berube said after the game.
The 29-year-old defender wears braces on both knees.
Grossmann, who is partnered with Mark Streit, had 175 blocked shots in the regular season. Teammate Andrew MacDonald led the NHL with 242.
The Flyers meet the Rangers Sunday in New York in Game 5. If Grossmann is not ready, a decision on his replacement likely comes down to this: Do you want size or speed?
If it's size, then the obvious choice is 39-year-old veteran Hal Gill. If it's speed, then it's Erik Gustafsson, who is 25 and less experienced.
Looking at how Berube uses his defense, he'll likely go with size, which would mean Gill would make his Flyers’ playoff debut.
