The Senators have recalled Swedish winger Andre Petersson and Kanata's Mark Borowiecki from their farm team in Binghamton.
But neither is expected to play in Tuesday's game at the Air Canada Centre versus the Toronto Maple Leafs.
After a morning meeting with his team, coach Paul MacLean said "at this point" he plans on going with the same lineup that lost 2-0 to the Winnipeg Jets Monday at Scotiabank Place. That includes in goal, where Craig Anderson will make his 10th consecutive start.
However, with the team heading on a four-games-in-seven-day west coast road trip following this Battle of Ontario, MacLean will lean on the extra bodies.
He said both players would make their NHL debut during the trip, whether it be in San Jose, Los Angeles, Anaheim or Phoenix.
Petersson, a fast and skilled winger with an abudance of offensive skills, has played particularly well for the B-Sens since Jan. 1.
Borowiecki has been solid all season.
"He's been a real good, hard working, dedicated player who really competes hard," said MacLean. "More in the physical defenceman, defensive defenceman capacity. In Binghamton, he's actually shown a lot of leadership with the injuries to their team. He's been their best defenceman.
"We're going on the road and we needed an extra defenceman. We wanted to make sure we rewarded Mark with the way he's played."
Meanwhile, the atmosphere at the ACC is expected to be like it was during the rivalry's zenith, with the Senators in fifth place and the ninth-place Leafs desperate to get back into the playoff picture.
"It's good that both teams are in the thick of it, in the second half," said Daniel Alfredsson. "I think that's a big thing to get the intensity going too, instead of one team trying to destroy it for the other, or take away points when they really don't have anything to play for. Tonight is an important game for both teams."
While Jonas Gustavsson had made six consecutive starts, James Reimer will get the assignment in goal for the Leafs against the Senators.Game time is 7 p.m.
