Luukkonen made 19 saves in a 3-0 loss to Toronto on Saturday.
Luukkonen gave up a goal in each period, including Auston Matthews' league-leading 60th tally of the season. The 25-year-old Luukkonen is in the midst of his best NHL season ever, compiling a 24-20-3 record with a 2.58 GAA and a .910 save percentage through 48 appearances. He has plenty of bounce-back appeal next week, with the Sabres set to play against Washington, Philadelphia and Detroit.
