The 24-year-old, a restricted free agent, accepted his qualifying offer.
Hackett played eight games with the Sabres late last season, going 1-6-1 with a 3.10 goals-against average and .908 save percentage. He was scheduled to undergo surgery after suffering a gruesome knee injury April 12 in Boston. The Sabres haven’t discussed his status for next season.
Hackett could return to Rochester, where he struggled in 2013-14, going 13-17-2 in 33 AHL appearances with a 3.07 goals-against average and .898 save percentage.
The Sabres acquired Hackett from Minnesota in the Jason Pominville trade.
