Brad Potts scored a deflected 95th-minute equaliser to spark wild celebrations as Preston North End denied runaway Championship leaders Norwich City a 10th win in 11 games.
Emi Buendia's stunning long-range effort looked to be enough to overcome manager-less Preston and earn the Canaries a win that would have set a new club record of 14 away league victories in a season.
The normally reliable Teemu Pukki had missed three great chances to be sure, unluckily seeing a fierce strike come back off the bar and also missing two wonderful one-on-one chances.
Preston took advantage of the away side's profligacy and avoided a fourth successive loss when Potts cut in from the left and found the corner of the net with a well-struck effort from the edge of the box.
