Buffalo was coming off a 4-3 win over Pittsburgh on Tuesday night in which it also erased a 3-0 deficit. The Sabres became the first team to win consecutive games when trailing by three or more goals since Dallas did it in January 2006 in beating Anaheim 4-3 in a shootout and Detroit 6-3.
Ilya Kovalchuk, registering his 600th career point, Bryan Little and Evander Kane scored for the Thrashers, 0-5-2 in their past seven games.
