Promotion-chasing Barnsley failed to capitalise on their dominance as they were held to a 0-0 draw at home to relegation-battling Cheltenham in League One.
The Tykes slipped seven points off the automatic promotion places and – with the four teams above them all playing each other – missed the chance to move up to fourth.
Cheltenham remain in the bottom four and are without a win in six, but the draw edged them to within four points of safety.
Jon Russell thought he had put the hosts ahead after four minutes when he turned home Luca Connell’s free-kick, but the assistant referee had raised his flag for offside.
The Tykes countered dangerously in the 31st minute as Adam Phillips slotted through to Sam Cosgrove, but his low effort from the edge of the box was always curling wide.
Cheltenham almost took the lead against the run of play in the 34th minute when Tom Pett curled one towards the bottom right corner from the edge of the box and prompted a smart save from Liam Roberts.
Russell should have broken the deadlock four minutes after the break when he was found at the back post by Cosgrove but dinked his close-range effort over the crossbar.
Barnsley substitute Devante Cole had an opportunity to make it 1-0 with eight minutes to play when a smart cross from Phillips gave the forward a free header inside the box, but he nodded wide.
