Crosby is doing light workouts, Pittsburgh Penguins Coach Dan Bylsma said in the first update on Crosby since his comments Dec. 12. At that time, Crosby said he had headaches and other symptoms but had passed a neurocognitive test.

Crosby missed nearly 10 months of action after being diagnosed with a concussion Jan. 6. He returned for the Penguins on Nov. 21 and played in eight games before his latest episode.
