Simon Cox hit a 41st-minute equaliser to deny Burnley a 1-0 half-time lead this afternoon.
The Championship leaders found themselves fortunate to be level after 20 minutes, as Henri Lansbury saw his curling free kick cannon off the crossbar, before Cox headed over from six yards out.
Billy Davies's men monopolised possession but, despite the territorial dominance, the visitors took the lead against the run of play.
Gonzalo Jara was adjudged to have handled Kieran Trippier's cross inside the area, before Sam Vokes stepped up and confidently dispatched the penalty to bag his 10th of the season.
Cox, who had earlier spurned a gilt-edged chance, soon made amends for the missed opportunity.
The Republic of Ireland could not miss this time, as the striker headed home from one yard out following a good cross from Jamie Paterson to restore parity on the stroke of half time.
