Wigan Athletic have dominated much of their must-win Championship clash with Bolton Wanderers at the DW Stadium, but it remains goalless at the break.
After a quiet opening 15 minutes with no goalmouth action at either end, James Perch came within inches of breaking the deadlock when his curling effort from range struck the crossbar.
Perch's spectacular shot seemed to wake the hosts up, and just a minute later Harry Maguire thumped a header over the top of the Bolton goal.
Josh Murphy then picked out Marc-Antoine Fortune, but the French striker delayed his shot and had to settle for a corner.
However, Wigan's spell of pressure was then interrupted by a swift counter-attack from the away side that culminated in Thomas Walker drilling an effort narrowly wide of Ali Al-Habsi's goal.
Leon Clarke thought that he had given his side the lead on the stroke of half time, but his effort was ruled out for offside.
