Norwich City were beaten in the Sky Bet Championship on Tuesday night, falling to defeat at home against Sheffield Wednesday.
The Canaries led 2-0 at the break but a three-goal salvo in 12 second-half minutes ensured that the Owls would come out on top.
Shane Duffy, Kenny McLean and Emiliano Marcondes all returned to the starting line-up, as Johannes Hoff Thorup shuffled the pack from Friday night's draw with Oxford United.
Norwich registered the game's first chance early on as Marcondes was played through, but the Dane's lifted effort was spurned by James Beadle in the Sheffield Wednesday goal.
Shea Charles headed over from close range for the Owls, getting up highest from Svante Ingelsson's long throw.
Just after the 15-minute mark, the Canaries were ahead. A slick move from Callum Doyle and Anis Ben Slimane saw the ball rolled into Borja Sainz, who beat Beadle and found the bottom corner.
And the lead would be doubled, courtesy of another fine passing move. Sainz's pass found Slimane, whose ball across goal was perfect for Ante Crnac to finish beyond Beadle.
In the second half, Djeidi Gassama curled an effort wide of Vicente Reyes' goal as the away side went in search of a route back into the game.
And they would find it when Michael Ihiekwe's header went through a number of bodies before finding its way beyond Reyes.
A Marcondes free-kick almost restored the two-goal advantage, but the Dane's effort took a deflection and over Beadle's goal.
The away side would soon find an equaliser. A number of shots were blocked, before Josh Windass fired in to level for the Owls.
Moments later, Sheffield Wednesday would find themselves in front. Windass fired a ball across goal which was met by Gassama who tapped into an empty net.
The Canaries are back in Championship action on Friday night, as they travel to Ashton Gate to take on Bristol City (KO 8pm).
