PITTSBURGH, Pa. - All-star forward Sidney Crosby has seen concussion specialists around the United States, the Pittsburgh Penguins said in a statement Wednesday.
The specialists have been monitoring Crosby's progress as he tries to shake headaches and other concussion symptoms.
The Penguins expect Crosby to be back in Pittsburgh for a few weeks, although no specific timetable has been set for his return to the ice.
"I appreciate all the support I've received from my family, friends, teammates and fans and from the entire Penguins organization," Crosby said. "I know they only want the best for my health, and for me to be fully ready when I return to game action."
Crosby suffered a concussion in early January and missed the rest of the 2010-11 season.
The 2007 NHL MVP made progress over the summer and took part in his normal off-season workout program that includes skating, shooting, stickhandling and off-ice work.
However, when Crosby got to 90 per cent exertion in his workouts, the headaches returned. At that point, his doctors and trainers altered his workouts accordingly.
He recently visited specialists in Michigan and Georgia.
"We've had him see leading specialists because we want to make sure he gets the best care possible," said Pat Brisson, Crosby's agent. "The Penguins always encourage their players to get second and third medical opinions and have been very supportive of this. And we've been talking to (Pittsburgh GM) Ray Shero every step of the way."
Penguins training camp opens Sept. 16 and Pittsburgh plays its first regular-season game on Oct. 6.
Brisson said Crosby's return won't be dictated by dates or games.
