What happened: David Kämpf signed a three-year contract with HC Litvínov of the Czech Extraliga, effectively ending his NHL career. The move comes shortly after the 31-year-old forward was acquired by the Buffalo Sabres from the Washington Capitals in a June sign-and-trade deal involving Alex Tuch.

Why it matters: The departure removes a recently acquired depth piece from Buffalo's roster ahead of the 2026-27 season. Kämpf brings extensive NHL experience to his new European club after deciding to move on from North America.

What to watch: Buffalo will evaluate alternative bottom-six forward options as offseason roster construction continues.
