Boston Bruins forward David Pastrnak will not play because of an undisclosed injury. He missed Boston's past two practices and is day to day, according to coach Claude Julien. Pastrnak is Boston's leading goal-scorer with 10, and has 14 points in 14 games. Forward Riley Nash will fill in on the top line with Brad Marchand and Patrice Bergeron. "It's about communication," Bergeron said. "With Riley, he plays a different game than [Pastrnak] obviously, but I don't think we have to think too much out there. It's about playing the game and making sure we're in position and things will fall in place." Nash has one goal and two assists in 16 games this season. The Bruins have won three straight games and are 7-2-0 in their past nine. They have scored 23 goals in that span, despite outshooting the opposition 322-236. "We'd like to obviously have more goals scored with the number of chances we've had," Julien said, "but at the end of the day we're winning hockey games, so you build on that stuff and you hope that the goals will come."
