Luukkonen (lower body) returned to practice Thursday, per Mike Harrington of The Buffalo News.
Luukkonen will partake in his first practice session in training camp. The 26-year-old starting netminder was 24-24-5 with a 3.20 GAA and an .887 save percentage across 55 regular-season contests in 2024-25. Luukkonen will be challenged for the top spot, as the Sabres signed Alexandar Georgiev and Alex Lyon to compete with Luukkonen and Devon Levi between the pipes.
