Wigan get revenge on Derby for Coyle axe
Derby lost for the first time in nine Championship matches as resurgent Wigan claimed revenge.
The Rams' 3-1 victory at the DW Stadium a month ago spelled the end for manager Owen Coyle, but his successor Uwe Rosler 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.
Makeshift striker Greg Halford scored his third goal in as many matches to put Forest ahead in the 36th minute, but Stephen Kelly headed the equaliser with the last play of the match.
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.
