A late Leeds equaliser denied Wednesday’s Under-23s all three points at Hillsborough in a second half that saw two goals apiece and honours even.
Ciaran Brennan and Liam Shaw scored either side of a Niall Huggins strike and the Owls looked on course to seal victory.
But in the final minute, Bryce Hosannah’s cross deflected off Shaw and found the net to see Leeds return home with a point.
Despite no goals in the first half, there were chances for both sides, the first of which came when Preslav Borukov broke through one on one but his effort was blocked by Illian Meslier, who returned to his feet to tip over Manuel Hidalgo’s lobbed effort.
Borukov had a second opportunity soon after, Waldock fed the Bulgarian down the left but his curling effort missed the target.
Leeds went on the offensive, and from Huggins’ corner, Olly Casey nodded over the crossbar.
Liam Waldock’s long range strike almost broke the deadlock, but the ball curled wide and into the side-netting.
New Whites signing Jean-Kevin Augustin might have put the visitors in front when he was burst in on goal but Joe Wildsmith tipped his strike wide for a corner.
Then Leeds came within a whisker of taking the lead when Liam McCarron’s cross deflected off Josh Dawodu and on to the Owls’ crossbar before going out of play.
There was a clear contrast in the second half, with chances being taken at both ends.
Leeds had the first opportunity which saw a magnificent piece of defending from Declan Thompson.
Huggins’ placed effort deflected off Wildsmith and was heading goalwards only for Thompson to clear off the line with an overhead kick.
The Owls’ next foray upfield would lead to the opening goal on the hour.
New Wednesday recruit Manuel Hidalgo was fouled on the right side of the Leeds box, his powerful low drive was parried by Meslier into the path of Brennan, who couldn’t miss from two yards out.
But Leeds went on the offensive and equalised on 72 minutes. Huggins struck a free kick from the left corner of the penalty area that evaded everyone and nestled into the far corner.
Wednesday, though, wasted no time in restoring their lead - less than a minute in fact.
Dawodu sent Shaw through on goal after a powerful run upfield and the midfielder made no mistake with a clinical strike across Meslier.
Wednesday controlled the game from then on, keeping possession well, and were defensively solid when called upon.
But, in added time, the away side drew level in fortuitous circumstances.
The ball was whipped in low at the near post by Hosannah and Shaw agonisingly turned into his own net to level the scores at the last.
Wednesday: Wildsmith, Dawodu, Galvin, Waldock, Brennan, Thompson (Lee 61), Hughes (Stobbs 79), Shaw, Borukov, Grant, Hidalgo (Preston 66)
