The Ottawa Senators can pull within one point of the Montreal Canadiens for first place in the Atlantic Division with a win against the Philadelphia Flyers and a Canadiens loss to the Dallas Stars on Tuesday. But the Senators might not have their full complement of forwards; Zack Smith isn't feeling well and will be a game-time decision, coach Guy Boucher said. If Smith can't play, Boucher said he'll use 11 forwards and seven defensemen. That would allow defenseman Jyrki Jokipakka to play for the first time since he was acquired in a trade with the Calgary Flames on March 1. Jokipakka has six points (one goal, five assists) in 38 games but hasn't played since Feb. 5. "He's a guy that's got good mobility, good size (6-foot-3, 215 pounds)," Boucher said. "He makes good, simple plays." This will be Ottawa's second of five straight road games, a segment the Senators believe is their most important of the season; it began with a 3-1 loss at the Canadiens on Saturday. "We talked beforehand this would be our most important road trip," forward Bobby Ryan said. "Coming in here, [the Flyers] are playing a lot better. … We can expect them to come hard early and often tonight. If we stick to the game plan, we'll be fine."
