Sheffield Wednesday are still searching for their first away victory since Carlos Carvalhal's appointment after slipping to a 3-1 defeat at promotion hopefuls Burnley today.
Strikes either side of half-time by David Jones, substitute Matthew Taylor and Andre Gray condemned the Owls to a second consecutive Championship defeat.
Wednesday held their own for the majority of an action packed contest and Atdhe Nuhiu cancelled out Jones' seventh minute opener.
But Carvalhal's men suffered their first loss at Turf Moor in 15 years as Taylor and Gray registered in the final 12 minutes.
Head coach Carvalhal made wholesale changes, making seven alterations to his starting line-up. He handed debuts to new signings Daniel Pudil, Barry Bannan and Fernando Forestieri.
With Keiren Westwood sidelined by a side injury, Carvalhal handed Joe Wildsmith his first Championship start, preferring the academy graduate in between the sticks over Lewis Price.
Liam Palmer, Glenn Loovens and Atdhe Nuhiu were also recalled, with Price, Jack Hunt, Vicent Sasso, Rhoys Wiggins, Alex Lopez, Marco Matias and Lucas Joao making way.
It is a sign of the strength of the depth Wednesday now possess that Hunt, Lewis McGugan, Wiggins and Modou Sougou were not even included in the match-day squad.
Wednesday got off to the worst possible start, falling behind in the seventh minute. Sam Hutchinson scythed down David Jones 25 yards out and the midfielder picked himself up to curl an unstopabble free-kick past Wildsmith.
It took the visitors a little while to regroup following that early setback. Nuhiu and Forestieri combined effectively before Daniel Pudil's cross was calmly gathered by Tom Heaton, who was part of England's squad during the international break.
The Owls levelled things up in the 20th minute when Nuhiu rose highest to power in Pudil's fine delivery. It was the giant striker's second goal of the campaign and the second year in a row he has netted at Turf Moor.
Burnley then enjoyed a good spell of pressure and Liam Palmer had to be alert to stop Michael Keane testing the reflexes of Wildsmith after the centre-back showed neat foot work inside the penalty area.
Moments later, Wednesday had a strong penalty appeal turned down after Forestieri appeared to be be brought down by Heaton after racing on to Nuhiu's flick on but referee Stephen Martin waved play on.
In an competitive, entertaining half, Bannan sliced a volley harmlessly over the top before Tom Lees produced a brilliant sliding challenge to deny Clarets home debutant Gray a sight at goal after good play by Michael Kightly.
Gray, Burnley's £6m club record signing, saw his low shot deflected narrowly wide before Keane hooked over as Owls' defence stood firm.
Wednesday threatened to unlock Burnley's defence for a second time after the re-start, with Forestieri's fierce driving sailing agonisingly over after the little Argentine was fed by Bannan.
Tom Lees snuffed out Scott Arfield's burst forward before Bannan peeled away to the back to nod Liam Palmer's looping centre off target.
Nuhiu and Forestieri linked well together just before the hour mark following a lightning counter attack which ultimately resulted in Nuhiu firing tamely at Heaton.
Wildsmith justfied his selection by producing an outstanding block to stop Gray from restoring Burnley's advantage.
Wallace, making his first return to Lancashire following his release by the Clarets over the summer, saw his cross turned shot fly wide before Wildsmith showed great reflexes to thwart George Boyd's deflected strike.
Carvalhal threw on Lucas Joao to try and inject some pace into his forward line after Taylor lashed a a venemous volley out of Wildsmith's reach in the 78th minute.
Forestieri bent a right foot over before Burnley wrapped up the points in added on time. Gray charged down Palmer's attempted clearance and rifled an effort through Wildsmith's legs.
