Pittsburgh Penguins center Sidney Crosby is back on the ice in Halifax, Nova Scotia, as part of his regular summer program, the team and his agent told the Pittsburgh Tribune-Review on Thursday.

Crosby missed the entire second half of last season after being diagnosed with a concussion Jan. 6.

His agent, Pat Brisson, told the Pittsburgh Post-Gazette that Crosby "has been skating for a while."

He last worked out on the ice in April before headaches returned and forced him to stop. People close to Crosby now believe those headaches were caused by a sinus infection, and not symptoms of the concussion, the Tribune-Review reported.

Crosby and Penguins general manager Ray Shero could not be reached for comment, the newspaper reported.
