James van Riemsdyk scored his fifth goal of the season, a wrester off the glove of Tim Thomas at 18:39 of the second period, and the Flyers lead the Bruins, 2-0 at the second intermission.

With Adam McQuaid and Jody Shelley both chasing an iced puck in the Bruins’ zone, Shelley pushed McQuaid — clearly the winner of the foot-race — and the defenseman’s momentum took him right into the boards, where he remained motionless for a few moments.

Shelley was handed a five-minute major penalty for hitting from behind and a 10-minute game misconduct. McQuaid returned to the ice later in the period.

The B’s outshot the Flyers, 13-7, in the second and lead them in shots, 22-17.
