According to a report, Sidney Crosby is back in Pittsburgh and is expected to be re-evaluated by a concussion specialist in the next week or so.
The Pittsburgh Post-Gazette said Saturday that Crosby still needs to be cleared before he can begin his off-season workout program.
The Penguins' captain has been sidelined since Jan. 6 when he was diagnosed with a concussion. Crosby was cleared to practice without contact in April but had to stop when he experienced headaches.
Penguins general manager Ray Shero told the newspaper that after Comrie struggled to return from hip surgery last season, he didn't know what the 30-year-old had planned.
"He might be leaning toward retirement," said Shero.
Kovalev, 38, was brought in from Ottawa during a March trade, but put up just two goals and seven points in 20 regular season games.
