The Golden Knights, who lost each game of a home-and-home against the Los Angeles Kings on Monday and Tuesday, hold an eight-point lead over the San Jose Sharks for first place in the Pacific Division, and trail the Nashville Predators by two points for the best record in the Western Conference.
The Senators, who have allowed four goals or more in five of their past nine games, will try to end a five-game losing streak (0-4-1). Ottawa, 2-6-1 in its past nine, is 17 points behind the Columbus Blue Jackets for the second wild card into the Stanley Cup Playoffs from the Eastern Conference.
