Sidney Crosby reportedly is back in Pittsburgh after a European vacation and is expected to be re-evaluated by a concussion specialist in the next week or so. The Pittsburgh Post-Gazette reported that Penguins general manager Ray Shero said Crosby will see specialist Michael Crosby. He still needs to be cleared before he can begin his off-season workout program. Crosby has been sidelined since Jan. 6 when he was diagnosed with a concussion.
