DERBY lost for the first time in nine Championship matches as resurgent Wigan claimed revenge yesterday.
The Rams' 3-1 victory at the DW Stadium a month ago spelled the end for manager Owen Coyle, but his successor Uwe Rosler (right) had a lot more success as Jean Beausejour's 69th-minute goal earned the visitors a 1-0 victory.
Derby had climbed into the automatic promotion places after a run of eight wins from nine matches, but they slipped to fourth as Leicester, Burnley and QPR all won.
Leicester are now four points clear at the top of the table thanks to their 3-1 victory against managerless Millwall.
Anthony Knockaert (six) and David Nugent (48) put the Foxes two up and, although Richard Chaplow (68) pulled one back, Jeff Schlupp made sure with an injury-time strike.
Burnley are back up to second after they held on to beat Huddersfield 3-2.
Danny Ings (six) opened the scoring and then put Burnley back ahead in the 41st minute after former Claret Martin Paterson (20) had levelled.
Kieran Trippier extended Burnley's lead in the 79th minute and that proved decisive, despite Paterson (89) scoring his second.
QPR's struggle for goals looked set to cost them again as Theo Robinson gave Doncaster the lead in the 43rd minute.
But Matt Phillips levelled 10 minutes after half-time and Charlie Austin struck in injury time to earn Rangers a 2-1 victory.
Nottingham Forest and Reading, two teams hoping to be in the promotion mix, had to settle for a point each in a 1-1 draw.
Bottom side Barnsley fought back well to earn a point at Birmingham, Jacob Mellis (61) cancelling out Nikola Zigic's 10th-minute opener.
Barnsley are level on points with Yeovil, whose match against Watford was postponed because of a waterlogged pitch.
Sheffield Wednesday climbed out of the bottom three with a 2-0 victory over Blackpool. Blackburn moved to within four points of the top six with a 2-1 victory over Leeds at Elland Road.
Bolton fought back to draw 2-2 with Middlesbrough, seventh-placed Brighton also left it late to draw 1-1 with Bournemouth and it was the same score between Charlton and Ipswich, who paid for David McGoldrick's missed penalty.
A Richard Wood own goal put hosts Ipswich ahead but McGoldrick saw his spot-kick saved by Ben Alnwick in the 79th minute and Johnnie Jackson struck in injury time.
