Nahki Wells and his Bristol City teammates return to Ashton Gate didn’t go to plan as, despite Wells heading home his third goal in Robins colors, they slipped to a second defeat in a row.
Connor Wickham’s free header gifted Sheffield Wednesday an early lead, with City’s task made all the harder when Massimo Luongo blasted the ball past Niki Mäenpää following a corner.
Garry Monk’s side looked arguably stronger for large periods, but City showed brighter spells particularly in the second half, forcing a way back into the fixture when Wells headed in from close range.
Right-back Zak Vyner came off the bench to make his first club appearance for over two years but he could only snatch at the chance to pull City level at the end, while Lee Johnson's men also had two penalty appeals dismissed.
The loss keeps Wells and teammates 12th in the Sky Bet Championship standings, five points behind sixth-placed Cardiff City with the gap between Bristol City and Sheffield Wednesday is now just three points.
