The Owls Under-21s were held to a 1-1 draw by Coventry City on Tuesday afternoon at Hillsborough.
Keenan King gave Wednesday the advantage right on half time and the hosts had the chance to double their lead after the break but Jack Stobbs struck his penalty over the crossbar.
Moments after the spot kick miss, the visitors levelled through George Thomas to earn a share of the spoils.
Jose Semedo, Alex Lopez and Joe Bennett were named in the starting XI and it was Semedo who went close to breaking the deadlock on 20 minutes.
The Portuguese almost profited as City goalkeeper Konrad Skuza parried a firm Stobbs effort into the six yard box, but the ball was cleared to safety before Semedo could make contact.
Coventry then went close as Aaron Phillips saw his looping header come back off the bar and Cameron Dawson was forced into action moments later, saving well from Gael Bigirimana’s free kick.
On the stroke of half time, King connected with a Stobbs cross from the right which Skuza could only parry back into the path of the Owls striker for a simple finish.
Just past the hour mark, Ryan Croasdale showed fantastic endeavour to burst into the box before tumbling under a challenge from Dion Kelly-Evans.
Stobbs hit over the bar from 12 yards and the Owls were made to pay minutes later as Thomas struck from close range after good skill from Ruben Lameiras.
There were good chances for both sides to go on and win the game, the first falling to Owls defender Brad Beatson, who guided his back post header just over the angle.
Dawson then made the save of the game to deny Kyle Spence, whose fierce effort was destined for the top corner but Dawson sprung to his right to superbly tip onto the bar.
Second half substitutes Warren Clarke and George Hirst almost combined to put the Owls ahead in stoppage time.
Clarke did well on the left to beat his man and deliver dangerously across the face of goal for Hirst, who struck agonisingly over the top.
