Victor Hedman does not know that it was his hit that gave Sidney Crosby a concussion. Fact is, most observers seem to figure it stemmed from a nasty shot to the head Crosby got from then-Washington center David Steckel four days earlier. Nonetheless, Crosby hasn't played since Hedman checked him from behind in a Jan. 5 game at Consol Energy Center, knocking Crosby's head off the glass. Crosby was diagnosed with a concussion the next day and sat out his 60th consecutive regular-season game Thursday night, when the Penguins visited Tampa Bay. Hedman, a Lightning defenseman, sounds as if he will be nearly as relieved as Crosby when Crosby finally gets medical clearance to resume playing.
