PITTSBURGH — Penguins star Sidney Crosby will miss his fifth consecutive game Saturday in Boston because of a concussion.

Penguins coach Dan Bylsma said Friday that Crosby isn’t ready to resume practicing or playing. Crosby won’t be allowed to return to the ice until he is symptom-free.

Crosby was sidelined after taking hits to the head in successive games Jan. 1 against Washington in the Winter Classic and Jan. 5 against Tampa Bay.
