Buffalo Sabres goaltender Robin Lehner is out because of an illness. Anders Nilsson will start and a goaltender will be called up from Rochester of the American Hockey League to be the backup, likely Linus Ullmark. Nilsson has started two of the past three games. "It helps a little bit to play more consistent and play more often," Nilsson said. "Usually you think a little bit less and just go out there and play." The Sabres see their come-from-behind 4-3 win against the Winnipeg Jets on Saturday as a potential turning point in their season, with the hope that the lessons learned in that game carry through for the rest of the season. "It starts with just how we start this game [Tuesday]," center Ryan O'Reilly said. "It's really important that we come out with that same energy and that mindset that we're not thinking, we're playing. I think the last two games we've got too much in our head thinking and you can see it. … That's what we have to establish right away, that this time of season … we have a good idea what we're going to see and it's about getting competitive and winning battles right away and that's what we have to do." Center Jack Eichel will play his 100th NHL game. He has 32 goals and 38 assists in his first 99 games. "You start to get to 100, 200 games and you're starting to be a veteran player," coach Dan Bylsma said. "To think he's already got his 100th, he's gotten it fast."
