Norwich City's faint hopes of making the play-offs in The Championship took a big blow after they lost 2-1 at home to Sheffield United.
The Canaries fell behind within the first six minutes when on loan Manchester United forward James Wilson put the Blades ahead.
Norwich, who made just one change from the side that took Chelsea all the way to penalties in their FA Cup replay in midweek, looked weary and rarely threatened.
Clayton Donaldson capitalised on a mis-hit back pass from Alex Tettey to double United's lead in the second-half, before Ivo Pinto pulled one back.
Norwich couldn't find an equaliser though and remain 13th - nine points away from sixth-placed United.
Ipswich Town also lost ground on the top six, although they did get a point at Bolton Wanderers thanks to Joe Garner's late strike.
Bolton went ahead when Gary Madine netted his 10th goal of the season, but Garner tapped into an empty net with eight minutes remaining to earn a draw.
In League One, Northampton Town moved out of the League One relegation zone with a 2-1 win over local rivals MK Dons at Sixfields.
First half-goals from John-Joe O'Toole and Chris Long sealed the three points.
The result means the Dons, who had Chuks Aneke sent off in injury time, replace Northampton in the bottom four.
At the other end of the division, there was a convincing victory for Peterborough United who saw off Oldham Athletic 3-0.
Junior Morias scored on his return from injury, while debutant George Cooper also hit his first goal for his new club. Jack Marriott put some added gloss on the scoreline with a 90th minute penalty as Posh moved up to 8th.
In League Two, Luton Two remain top after a hard fought 1-0 win over Morecambe, while Cambridge United were thrashed 5-2 at Forest Green Rovers - despite taking the lead twice.
Colchester United drew 1-1 against Grimsby Town, with Sean Murray netting their equaliser, and Stevenage and Carlisle United played out a goalless draw.
