The Lightning, which won eight consecutive games from Nov. 29-Dec. 3, have outscored opponents 35-12 during their seven-game winning streak. They have the best record in the NHL and have a 16-point lead on the Boston Bruins for first place in the Atlantic Division.
Lightning forward Nikita Kucherov, who leads the NHL in scoring with 99 points (29 goals, 70 assists), can become the first player in Tampa Bay history to score 100 points in multiple seasons; he had 100 points (39 goals, 61 assists) in 80 games last season.
Defenseman Victor Hedman will be a game-time decision because of a lower-body injury that caused him to miss a 5-2 win at the Philadelphia Flyers on Tuesday.
The Sabres, looking to avoid their fourth straight loss, have been outscored 14-5 in three consecutive defeats and are 3-6-1 in their past 10 games. Buffalo is six points behind the Columbus Blue Jackets for the second wild card into the Stanley Cup Playoffs from the Eastern Conference.
