Luukkonen made 37 saves in Wednesday's 6-5 overtime loss to the Penguins.
The Sabres held a 3-1 lead after the first period, but Luukkonen saw it slip through his fingers on a night when both Sidney Crosby and Evgeni Malkin turned back the clock en route to some big personal milestones. After a breakout 2023-24 campaign, Luukkonen has stumbled out of the gate this season, going 0-2-1 with a 3.69 GAA and .874 save percentage in three starts.
