Jordan Rhodes' dramatic last-minute winner sealed three crucial points in Sheffield Wednesday's survival battle.
The Owls' 2-1 success at Bournemouth represented a fourth Championship defeat in a row for Jason Tindall's promotion-chasing side.
Callum Paterson gave Wednesday a first-half lead when he pounced on Jack Stacey's weak pass and stabbed beyond keeper Asmir Begovic.
Bournemouth improved in the second half and Junior Stanislas levelled from the spot after Sam Surridge had been brought down by Sam Hutchinson.
Against the run of play, Wednesday broke in the 90th minute and Rhodes headed home Kadeem Harris's right-wing cross.
