Buffalo Sabres face a rocky season start as Ukko-Pekka Luukkonen lands week-to-week with a lower-body injury, leaving goaltending duties to Alexandar Georgiev and Alex Lyon. The blue line is thin with Michael Kesselring hurt and Owen Power and Mattias Samuelsson nursing undisclosed injuries, though both are expected to be ready for the opener against the New York Rangers after a 5-3 preseason loss to Pittsburgh. Fantasy angle centers on early goaltending volatility and defensive depth in the opening week.
