The Owls’ Development Squad shared the spoils with Crystal Palace with an entertaining 2-2 draw at Middlewood Road.
Palace twice came from behind to claim a point, leaving the home side ultimately frustrated.
The likes of Jake Kean, Urby Emanuelson, Modou Sougou and Glenn Loovens were each given outings for the hosts.
After a goalless first half, the contest exploded into life in the second period.
Matt Penney gave Wednesday the lead on 64 minutes, firing home a superb free kick from 20 yards.
The Eagles, though, equalised with a set piece of their own 14 minutes later as Luke Dreher found a way past Kean between the sticks.
But Wednesday were far from finished and Devante Rodney fired Neil Thompson’s side in front on 80 minutes – only for Palace to level with eight minutes remaining through Randell Williams.
The Under-23s are next in action on Monday 19 September against Watford in Hertfordshire.
