Luukkonen turned aside all 13 shots he faced during Tuesday's 5-1 preseason win over the Blue Jackets.
Luukkonen made his first start of the 2026-27 preseason Tuesday and played two periods. Colten Ellis entered the game in the third period. Luukkonen will battle Alex Lyon for playing time this campaign, and Ellis could be in the mix. Across 35 regular-season appearances with Buffalo last year, Luukkonen went 22-9-3 with a 2.51 GAA and a .909 save percentage.
