A concussion "is just the worst injury"
 

The Crosby injury, NHL-leading goal scorer Steven Stamkos of the Tampa Bay Lightning says, was “the thing that made it go over the top.” If a concussion could sideline, perhaps forever, a player as skilled as Crosby or as tough as Philadelphia Flyers defenceman Chris Pronger, then it has made all players realize they could be next.

Claude Giroux, a leading point-getter up until he was sidelined with a concussion, says it “is just the worst injury.” Seven of his Philadelphia teammates have been lost to the injury this year.
