Season Series: This is the fourth of five meetings between the Northeast Division rivals. The Bruins are 3-0 with one win in regulation, one in overtime and one in the shootout.
Big Story: Boston is fighting Montreal for the lead in the Northeast Division, but the Ottawa Senators aren't too far behind. They are four points behind the Bruins and are starting a critical seven-game road trip at TD Garden.
Senators: They are coming off a 4-0 loss at home to the Toronto Maple Leafs on Saturday. The Senators put 31 shots on goal, including 26 over the final 40 minutes, but couldn't solve Leafs goalie James Reimer.
The Senators had won three straight prior to the loss to Toronto.
"When we win, we say we have to go on to the next game," Senators forward Guillaume Latendresse said. "When you lose, you have to do the same thing. ... We're playing against Boston, and that's what we have to do now."
Robin Lehner, who has been in net for all three games against the Bruins, is expected to start Tuesday night. He allowed two goals in each of the three previous games, including a 44-save effort in his season debut on Feb. 28.
Bruins: Boston is coming off a much-needed 2-0 win over the Buffalo Sabres on Sunday. The Bruins lost to the Philadelphia Flyers on Saturday and blew a lead in the third period and lost in a shootout, 6-5, to the Montreal Canadiens last Wednesday.
"I think we're going to call it a step forward," Bruins coach Claude Julien said following the game Sunday. "The effort [Sunday night] was much better. We're skating better."
The Bruins recent skid cost them their lead in the Northeast Division to the Canadiens.
Krejci and Horton each had a goal and an assist. Lucic contributed on Horton's goal, which came with 4:16 left in regulation.
Who's hot: The Senators just got shut out by the Maple Leafs, so anyone who was hot isn't anymore. However, forward Mike Zibanejad had a four-game point streak going prior to that game. For the Bruins, they need the Krejci line to stay hot. Krejci scored his first goal in seven games and just his second in 12 against Sabres. Horton got his third in as many games.
