The Owls Under-18s picked up a point on the road on Saturday in a goalless draw with Millwall.
There was very little to separate the two sides in the 10.30am kick-off at Calmont Road and a point apiece was a fair reflection of the 90 minutes.
Wednesday began the game in a lively mood and created several half chances inside the opening 15 minutes but it was the hosts who came close to registering an early goal.
Millwall striker Henry Hearn was sent through one-on-one in the 12th minute but was stopped in his tracks by a well-timed Josh Chapman last ditch challenge.
With an equal share of possession and chances, the two sides went back in at half time locked at 0-0 though Wednesday did go close twice right on the stroke of half time.
First, Murtadha Al-Jahadhmy worked his way down the flank before pulling the ball back to in-form striker Bailey Cadamarteri, who struck just wide of the post.
Then Tony Yogane used his pace and trickery to create a yard of space for Rio Shipston, who took on a long range effort that produced a good save from Lions goalkeeper Ryan Hammond.
Wednesday had to weather an early second half storm and did so thanks to an excellent save from Pierce Charles on 55 minutes to deny Tom Leahy and Cian Flannery was well placed to clear a follow up attempt off the line.
Sean Fusire and Leojo Davidson combined well 20 minutes from time, but the latter was denied from inside the 18-yard box as Hammond made another smart save to keep the score level.
A draw a fair result in the capital and the Wednesday youngsters are next in action on Saturday at home to Bristol City (1.30pm).
Owls: Charles, Fusire, Chapman, Flannery, Sesay, Asfha (Maltby 65), Shipston, Davidson, Yogane (Maciag 75), Cadamarteri, Al-Jahadhmy
