West Ham are now four points off the top two in the Championship after they were held to a draw as Southampton and Reading both won.
Leaders Southampton made no mistake in their home clash with Doncaster at St Mary's and it was former Rovers star Billy Sharp who did the damage with two goals in the second half.
Likewise Reading secured all three points as they cruised to a 3-1 win over Blackpool at the Madejski Stadium.
The Royals' win now means they are clear in second after West Ham's failure at Burnley as they were held to a 2-2 draw.
But things could and should have been much worse for West Ham as they trailed 2-0 at the break, but Kevin Nolan and James Tomkins rescued a share of the spoils for Sam Allardyce's men, who have now drawn their last five games.
Brighton & Hove Albion remain in fourth after a 1-1 draw at Nottingham Forest . Sam Vokes' second-half header looked to have won it before Joel Lynch claimed a last-minute equaliser.
Middlesbrough are up to fifth, but they again failed to win on home soil as they came from behind to draw 1-1 with lowly Bristol City at The Riverside with Malaury Martin grabbing the equaliser.
Hull City missed the chance to move back into the play-off zone after they lost 2-1 at former boss Nigel Pearson's Leicester City. Matt Fryatt had opened the scoring against his former club but two goals in 60 seconds from Lloyd Dyer and Ben Marshall did the damage.
Leeds United's play-off hopes remain intact after they claimed a 1-0 win at Millwall thanks to Ross McCormack's goal.
Coventry City moved to within a point of safety after a 2-0 win over basement side Portsmouth at the Ricoh Arena, thanks to second-half goals from Gary McSheffrey and Oliver Norwood.
Derby County moved into the top half of the table after a 3-2 win over Crystal Palace at Pride Park. The Rams were three goals to the good, but only just managed to hang on after a second-half comeback from the visitors.
Watford came from behind to clinch a 2-1 win over Ipswich Town at Vicarage Road. Jay-Emmanuel Thomas had put Town ahead but goals late in the second half from Sean Murray and Troy Deeney sealed all three points for the Hornets.
Finally, Barnsley moved 11 points clear of the relegation zone and moved above Peterborough after a 1-0 win over the Posh at Oakwell thanks to David Cotterill's goal.
