Port Vale lost to high-flying Leyton Orient as their slim play-off hopes were dealt a blow.
Micky Adams’ side had the opportunity to close in on League One sixth-placed Peterborough but were beaten 2-0 at Vale Park by the London outfit.
Dean Cox and Nathan Clark netted for the Orient as the Valiants had two goals ruled out and hit the bar through Billy Knott.
Despite periods of pressure from Vale, they could not breach promotion-chasing Orient’s solid defence and the Staffordshire side remain tenth in the League One table.
Burton Albion missed an opportunity too as they played out a goalless draw with a struggling Portsmouth side in League Two.
Gary Rowett’s men had more efforts than Pompey, with Billy Kee firing the best chance high and wide, but they lacked a clinical edge.
Their rivals for automatic promotion Rochdale had a shock defeat at bottom club Torquay but the Brewers couldn’t leapfrog them into third spot, instead closing to within a point.
Crewe Alexandra also suffered disappointment but gained a point away at Walsall.
They took the lead at the start of the second half through Chuks Aneke but Mark Ellis headed into his own net in the 91st minute to make it one apiece.
The win would have lifted the Alex out of the bottom four but they still close in on safety after Tranmere and Stevenage also failed to win.
