The Boston Bruins, who have lost two of their past three games, will not have captain Zdeno Chara in the lineup against the Ottawa Senators. The defenseman sustained a lower-body injury in the Bruins' 4-2 loss to the St. Louis Blues on Tuesday and is expected to miss at least two games, Bruins coach Claude Julien said. Defenseman Kevan Miller, who has not played this season because of a hand injury, will be a game-time decision. When asked about making up for Chara's absence, Julien said, "We do things by committee here. We've missed [Patrice] Bergeron at the start of the season, we've missed [David] Backes, [David] Pastrnak. We don't use those as excuses. We just move on." Pastrnak will play against the Senators after missing the past three games with an upper-body injury. Bruins goaltender Tuukka Rask has won 11 of his 14 starts and is tied with Carey Price of the Montreal Canadiens for most wins. Rask has a 1.15 goals-against average in his past seven starts and his 1.57 GAA for the season is the best in the League. Bruins forward David Krejci has two goals in 19 games. Bergeron has three goals in 16 games; he had six goals and 10 assists through 16 games last season.
