Sergiu Bus was on target twice for the Owls Development Squad in the 2-2 draw with Brentford on Tuesday afternoon at Middlewood Road.
Wednesday started strongly but fell behind to an early Montell Moore strike.
The hosts responded well to that set back inside the first five and James Demtriou hit crossbar following good work from Bus in the final third.
The Romanian striker then came within a whisker of levelling the contest with a fierce shot from outside the box that was destined for the top corner, but for a fine save from the Bees goalkeeper.
Wednesday pressed for the equaliser before the break as Matt Penney drilled inches wide from 20 yards moments before Bus restored parity.
Penney fed Demtriou down the left, who delivered a low ball into the box that bobbled its way into the path of Bus and the striker took a touch before firing into net.
Moments after the restart, Ryan Meadows hit first time over the bar from Luke Booker’s centre and Claude Dielna was unlucky to see his well struck free kick fly just over the top.
But the Owls were hit on the break 12 minutes from time as Moore sprung the offside trap before cutting back across goal and unleashing a devastating low finish into the net.
Wednesday, though, drew level once more two minutes from time when Bus pounced in the box to capitalise on hesitation at the back, to rescue a point for the Under-21s.
Owls: Dawson, Booker, Wildin, Kirby, Lachman, Dielna, Meadows, Clarke, Bus, Demtriou (Hirst 79), Penney (Nicholson 51)
