Sidney Crosby still feeling concussion symptoms

Sidney Crosby is still suffering some concussion symptoms, says Pittsburgh Penguins coach Dan Bylsma.

Speaking to reporters on Wednesday, Bylsma said Crosby has been participating in light workouts.

Crosby has not played since Dec. 5. and was placed on the Penguins' injured reserve list on Dec. 17.

He was originally injured last January after taking hits to the head in consecutive games, causing a concussion.

Crosby returned for eight games this season before his latest absence, picking up 12 points over that span.
