Ipswich hosted Leeds at Portman Road, and earned a 2-1 win.
Ipswich Town snatched a late winner against Leeds to end the Whites' eight game unbeaten run in all competitions.
Brett Pitman struck the goal in injury time to complete a second half turnaround for the hosts.
Former striker Noel Whelan told BBC Radio Leeds: "A point would have been really good this evening, we didn't create too many chances.
"It's just demoralising, football's a cruel games sometimes."
Souleymane Doukara had put the visitors ahead, netting after just 13 seconds, the fastest goal in the Championship this season.
Leeds led at half-time, but Luke Chambers pulled the hosts level shortly afterwards, netting in the 50th minute.
Doukara had started up front for Leeds, with striker Chris Wood out injured and Mirco Antenucci left on the bench. He was brought on to chase the game with 11 minutes to go, but to no avail.
New signing Mustapha Carayol also started, as did Sam Byram, whose future at the club remains unclear.
Ipswich had gone into the fixture nine points ahead of the Whites, and had won 1-0 at Elland Road earlier in the season, and that gap is now extended.
