Vigneault did confirm Lundqvist would start Sunday's game against Ottawa.
The Rangers and Senators meet for the first time since Ottawa beat the Rangers in a six-game series last spring.
Like the Rangers, Ottawa enters tonight's game with losses in two straight, including an overtime loss to Arizona Saturday night.
New York will get its first look at Matt Duchene in an Ottawa jersey tonight following the three-team trade that sent him north from Colorado. The deal added more firepower to a Senators squad with several weapons up front and on the back end.
Mark Stone leads the team with 13 goals and 20 points, followed by defenseman Erik Karlsson's 17 points in 13 games. Mike Hoffman is off to a good start with 16 points, while former Ranger Derick Brassard has 15 through 18 contests. Duchene, meanwhile, is pointless through four games as a Senator.
Goaltender Craig Anderson is 7-4-3 with a 2.92 GAA and a .898 SV% in 14 games (13 starts). He's expected to start against the Rangers after serving as the backup Saturday night.
