Pittsburgh pregame housekeeping

Before the puck drops, here’s a quick update on the lineup for the Bruins and Penguins:

•Michael Ryder, a game-time decision, is in. That leaves Jamie Arniel, up on emergency recall, as a healthy scratch.

•Tim Thomas and Brent Johnson start in goal.

•Deryk Engelland, who has emerged as a feared fighter this season, is a healthy scratch.
