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 was progressing, but isn't ready to resume practicing or playing. Crosby will not 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.

Crosby showed no signs of a concussion after absorbing a blind-side hit from the Capitals' David Steckel and was allowed to play against Tampa. The NHL's leading scorer was rammed headfirst into the boards by the Lightning's Victor Hedman in that game and has not played since.

The Penguins are 1-2-1 without Crosby.
