What happened: The Buffalo Sabres and Ottawa Senators will face off four times during the 2026-27 NHL regular season. The Senators enter the upcoming campaign with a revamped roster after losing Brady Tkachuk in the offseason. Ottawa has added several new pieces, including William Eklund, Samuel Ersson, and Andre Burakovsky.

Why it matters: With an expanded 84-game schedule, the four matchups will be critical for playoff positioning in the Eastern Conference. The Sabres are looking to establish early dominance after reaching the second round last postseason. Meanwhile, the Senators must integrate their new additions to stay competitive in the Atlantic Division.

What to watch: The Sabres and Senators will play their first game of the season series on November 4 in Buffalo. Three of their four matchups are scheduled before the March 1 trade deadline.
