Crosby -- who missed much of the last two seasons with concussion and neck problems -- told the Pittsburgh Post-Gazette after an informal workout with teammates Tuesday he is in good health.
Asked if he had experienced any health setbacks over the summer, he told the newspaper, "It's been really good. Nothing. I've been feeling 100 percent. It feels good to not have to think about that, and to work as hard as you want."
The Penguins superstar said he's eager for training camps to begin but is also wary of a possible lockout when the NHL's collective bargaining agreement expires Saturday.
"It's a little bit of a tricky situation," he said.
Crosby confirmed to the Post-Gazette he will consider offers to play in Europe if the lockout drags on.
The NHL Players Association was set to meet Wednesday in New York as a league-imposed deadline for a new deal approached.
