Burnley took pole position in the race to win automatic promotion from the Sky Bet Championship while Middlesbrough suffered an unexpected setback on Tuesday night.
The Clarets are now four points clear of Boro in first place after rallying from behind to beat Fulham 3-2 at Craven Cottage.
Sam Vokes' early opener was cancelled out by Ross McCormack and the Cottagers soon took the lead through Moussa Dembele.
Wales striker Vokes levelled the tie from the penalty spot four minutes after half-time, leaving Andre Gray to snatch all three points with a 61st-minute winner.
Boro were beaten 1-0 by Neil Warnock's resurgent Rotherham as Lee Frecklington's 88th-minute strike brought the Millers to within a point of 21st-placed MK Dons and safety. Karl Robinson's men kept their heads just above water, for the time being, by taking a point from a goalless draw at Charlton.
Brighton also drew a blank against Sheffield Wednesday at the Amex Stadium but their share of the spoils saw them rise to third, where they are two points behind Middlesbrough.
With Hull facing Arsenal in the FA Cup instead of participating in league action, the opportunity was there for fifth-placed Derby to make up ground on the Tigers, who were busy losing 4-0 at home to Arsene Wenger's Barclays Premier League giants.
It was a bad night for the Rams, too. Tjaronn Chery continued his good run of form in front of goal by opening the scoring as QPR downed Derby 2-0 at Loftus Road, with Gabriele Angella rubber-stamping victory for the Londoners at the death.
Leeds damaged 10-man Cardiff's bid to reach the play-off places by completing a double over the Bluebirds thanks to goals from Souleymane Doukara and Mirco Antenucci. Fabio was dismissed after an hour's play in Glamorgan.
First-half efforts from Tony Watt and Danny Graham fired Blackburn to a 2-0 home victory over Birmingham while Ipswich were held to a 2-2 draw at Bolton.
Kevin Bru and Christophe Berra put the Tractor Boys in control but Lawrie Wilson's response ensured there would be a tense finale at the Macron Stadium. Then, seven minutes into time added on, substitute Stephen Dobbie scored from the penalty spot to check Ipswich's rise up the table.
Elsewhere, Nottingham Forest and Wolves earned good wins to consolidate their status as mid-table battlers. Nelson Oliveira's 37th-minute goal was all that separated Forest and Preston in a 1-0 home win at the City Ground and Wolves left it late to edge Bristol City 2-1 in the West Midlands.
Nathan Byrne put Wolves ahead just after half-time but an Aden Flint equaliser looked like dividing the points at Molineux - at least until Matt Doherty headed home a stoppage-time winner to make it back-to-back home wins for Kenny Jackett's side.
