A goal deep into injury-time by Darren O'Dea earned Leeds a win against 10-man Peterborough.
Leeds went ahead through Andy Keogh's stunning volley but Gabriel Zakuani levelled with a powerful header.
Peterborough striker Lee Tomlin saw red for a challenge on Keogh before Leeds regained the lead when Adam Clayton took Lloyd Sam's pass and stroked home.
Mark Little thought he had earned Posh a point when he bundled in, only for O'Dea to head the winner.
Leeds took the initiative as early as the fourth minute when Keogh hit a superb shot, which gave home goalkeeper Paul Jones no chance.
Peterborough sprung to life after the goal and were level 19 minutes later when Zakuani headed home his first goal of the season.
The home side were reduced to 10 men on 37 minutes, when Tomlin was red-carded for a late challenge on Keogh.
And the visitors made their advantage pay nine minutes after half-time, when Clayton stroked home his third of the season following good work from Sam and Danny Pugh.
With just two minutes to go it looked as though goalkeeper Paul Rachubka had cost his side the points.
The former Huddersfield and Manchester United shot-stopper was caught in no man's land as a ball sailed into his box and he got tangled up with his own defenders, allowing Little to force in from six yards.
But Rachubka, who gifted Coventry a late equaliser on Tuesday, breathed a sigh of relief when O'Dea secured the win.
O'Dea, who Posh felt should have earlier seen red for bringing down David Ball when he was the last defender, flicked in Clayton's free-kick to have the final word five minutes into stoppage time.
