Challinor, having been announced as Henrik Pedersen’s successor on the morning of the match, saw his new team make a solid start at Hillsborough as Davis Keillor-Dunn put them ahead in the 25th minute.

Keillor-Dunn pounced on a misplaced pass and ran from the centre circle unchallenged before firing a low shot which went inside Bailey Peacock-Farrell’s right-hand post.

The hosts found themselves a man down five minutes before the interval, however, when Sil Swinkels was shown a straight red card after bundling over Tom Bloxham as the forward looked set to go through on goal.

Keillor-Dunn went close to scoring a second goal when his long-range effort forced a good save from Peacock-Farrell.

And then Blackpool substitute Jerry Yates, like Peacock-Farrell a former Wednesday loanee, equalised, poking the ball past Ashley Maynard-Brewer in the 81st minute following Albie Morgan’s cross.

Mason Burstow had one last chance to restore the Owls’ lead when he produced an audacious chip from distance, but Peacock-Farrell managed to claw it away.
