After spending the last three games getting comfortable with the Garden, the Bruins, undefeated on the road this season, are in Ottawa and set to take on the Senators in their second-straight game against a division rival. The Senators are 4-5-1 on the season, good for nine points, just one better than last-place Buffalo in the Northeast division.

- Tim Thomas will be in net for the Bruins, and manning the pipes for the Senators is 30-year-old Brian Elliott. Now in his third season with the Senators (he started one game in the 2007-08 campaign), Elliott hasn’t put up the prettiest numbers, posting a 3.27 goals against average and a .900 save percentage. The numbers look even worse when put up against Thomas’ league-leading 0.60 GAA and .981 save percentage. Thomas is 16-7-2 against the Senators in his career with a 2.10 GAA and .932 save percentage.

- Thomas’ chief concerns will be Daniel Alfredsson, who has six goals and six assists on the season, as well as Jason Spezza. The latter is returning from a groin injury that kept him out for the Sens’ last four games, though Ottawa has won their last two.

- Left wing Milan Michalek is out for about a week for the Senators thanks to tendinitis in his surgically repaired left knee. Michalek has four goals and an assist in eight games played this season.

- Old friend Sergei Gonchar was honored by the NHL on Tuesday as he dressed in his 1000th career NHL game. The Russian defenseman, who finished out the 2003-04 season and playoffs with the Bruins after a deadline deal with Washington, was inked to a three-year, $16 million deal by the Senators after playing the previous five seasons in Pittsburgh. Now 36 years of age, Gonchar has six assists on the season.

- For the Bruins, Nathan Horton’s season-opening point streak ended in Thursday’s 2-0 victory over the Maple Leafs, but he still leads the B’s with nine. The only change the Bruins have seen to roster was Friday’s move that sent Brian McGrattan to Providence for the weekend for conditioning. The move will have no impact on Saturday’s lineup, as McGrattan had been a healthy scratch in all five games he’s played in since signing with the Bruins.

Here are the lines, according to the Globe’s Fluto Shinzawa:

Milan Lucic – David Krejci – Nathan Horton

Jordan Caron – Patrice Bergeron – Blake Wheeler

Mark Recchi – Tyler Seguin – Michael Ryder

Brad Marchand – Gregory Campbell – Shawn Thornton

Zdeno Chara – Andrew Ference

Matt Hunwick – Dennis Seidenberg

Mark Stuart – Adam McQuaid
