Crosby may participate in game-day skates beginning Thursday, Penguins General Manager Ray Shero said. However, Crosby hasn't been cleared for full practices and it is unclear when he might return for games.
Shero said "I don't believe" Crosby would rejoin the team before the end of the regular season.
Crosby has missed 36 games since being injured. Pittsburgh is 19-12-5 in those games and has wrapped up an NHL Eastern Conference playoff spot. Even though he's missed nearly three months of play, Crosby leads the team with 32 goals and 66 points.
It is thought Crosby was injured in the Penguins' Jan. 1 game against the Washington Capitals although he played Jan. 5 when he suffered another hit to the head in a game against Tampa Bay.
