Preston North End took advantage of Cardiff City's slip-up on Friday after a 1-0 victory at Leicester City.
Patrick Agyemang's strike on the quarter-hour mark meant The Lilywhites pulled level on points with The Bluebirds at the summit of The Championship.
He struck home on the rebound after defender Sean St Ledger initially hit the Leicester post, as Paul Simpson's side claimed all three points in the Midlands.
Earlier on Saturday, Birmingham City missed the chance to go level with Cardiff after a 1-1 draw with Wolverhampton Wanderers in the West Midlands derby.
Blues boss Steve Bruce will be rueing his side did not turn their first-half dominance into goals in the noon-hour kick-off at St Andrews, despite taking a deserved lead on the half-hour mark.
Summer signing Gary McSheffrey struck his fourth goal in five Championship games when he beat goalkeeper Matt Murray with a dipping volley from the edge of the Wolves box after the former Coventry City man latched on to a Nicklas Bendtner header.
For all of their dominance in the first half, Wolves worked their way back into the contest and eventually claimed a point when Jody Craddock headed home from a flicked Rohan Ricketts's corner in the dying stages.
Blues were furious with the equaliser, as referee Mark Halsey waved play on after Wolves defender Gary Breen appeared to have struck Birmingham's Sebastian Larsson with an elbow before Ricketts's corner.
Bruce's frustrating day was compounded when referee Halsey chalked off a second Birmingham goal in injury time for an offside decision on Bendtner, and both sides had to settle for a share of the spoils.
West Bromwich Albion claimed three valuable points against fellow high-flyers Burnley after a 3-0 home success.
Jason Koumas (5) gave The Baggies the lead before Nathan Ellington (7) doubled the Black Country club's advantage.
Darren Carter struck a third just before the break for West Brom, as The Clarets had Frank Sinclair sent off for a second bookable offence 12 minutes from the end at The Hawthorns.
Derby County defeated Luton Town 2-0 at Kenilworth Road, with goals from on-loan Jon Stead (72) and former Luton striker Steve Howard (75).
Stoke City are two points outside the play-off places after a 2-0 win at Hull City.
A Danny Higginbotham header after two minutes gave The Potters the lead before Darel Russell (80) sealed the points for Tony Pulis's side at The Kingston Communications Stadium.
Southampton are also two points off the top six after an impressive 3-0 win at struggling Leeds United.
Grzegorz Rasiak (29) gave The Saints the lead before Rudi Skacel (69) doubled the visitors' advantage at Elland Road.
Six minutes later, Rasiak got his second goal for the South Coast club, as Leeds sit third from bottom in the table as a result of Saturday's defeat.
Plymouth Argyle missed the chance to move into the play-off places after a 1-1 draw at bottom club Southend United.
Bojan Djordjic (5) gave The Pilgrims an early lead after converting a Paul Connolly cross.
However, Mark Gower (59) earned a point for The Shrimpers at Roots Hall, who sit four points adrift of safety in the table.
Coventry City defeated nine-man Sheffield Wednesday 3-1 at The Ricoh Arena.
In an eventful contest, The Owls had Wade Small sent off for violent conduct (16) before they claimed the lead through Chris Brunt (22).
The Sky Blues levelled though a Madjid Bougherra own-goal three minutes later before Brunt was given his marching orders for a professional foul (37).
Micky Adams's side then claimed the points through a second-half brace from Leon McKenzie (51, 55).
Sunderland defeated Colchester United 3-1 at The Stadium of Light, with Stephen Elliott (45, 53) finding the scoresheet twice for The Black Cats.
