Boss Carlos Carvalhal refused to criticise Jeremy Helan after the Frenchman’s dismissal in the Owls’ thrilling away win at Brentford.
Helan, brought on as a substitute for injured full-back Daniel Pudil, was given his marching orders after picking up two yellow cards in the space of 14 second-half minutes.
His indiscipline could have cost Wednesday maximum points, with his second booking coming a minute after Alan Judge’s leveller.
But striker Lucas Joao spared Helan’s blushes, seizing on a mistake by Bees defender Jack O’Connell before firing home to send the Owls 1,500-plus fans into raptures.
Carvalhal said: “I’m not disappointed with him.
“I am here to support the players and give confidence to them.
“He made one or two mistakes today but I recognise he had an absolutely fantastic game against Newcastle. I prefer to talk positively. He did fantastic in the balance of the week.”
After Helan’s red card, Barry Bannan dropped back to fill in on the left side of the Owls’ defence. The midfielder has impressed since joining the Championship club on a free transfer.
Carvalhal commented: “Barry can play all positions. He dropped into full-back and can play anywhere.
“He is someone who all coaches like because he’s a complete player. He is a very hard worker with good quality and understands football. If we put him in central defence, he could probably do a job there!”
Carvalhal, who would have had no complaints had Wednesday come away with just one point, rewarded his players by giving them yesterday and today off from training.
“We now have a couple of days’ rest and some time to prepare for the next match; we deserve that and I need it a little bit to relax,” said the former Sporting Lisbon and Besiktas chief. “It has been a very stressful period. The Championship is a relentless league.”
