Burnley were made to wait to clinch the Championship title after being held to a 2-2 draw at Rotherham.
Having ensured an immediate return to the Premier League 11 days ago, Scott Twine's left-footed volley from the edge of the box gave the Clarets the lead.
Shane Ferguson's inswinging corner on the stroke of half-time bamboozled Burnley with Vininho getting the final touch as he put the ball into his own net.
The away fans were celebrating after Manuel Benson's superb curling left-footed effort into the top left corner restored the lead, but Georgie Kelly equalised from close range with five minutes to go.
