The Owls got their impressive away form back on track with a point from the Yorkshire derby clash with Leeds at Elland Road.
Chris Maguire gave Wednesday the lead after 52 minutes with a thumping strike.
But defender Giuseppe Bellusci equalised for the hosts with 11 minutes to go.
The Owls had been somewhat fortunate to go into the break with the goalless after a first half spent largely on the back foot.
But a much improved second half show from Stuart Gray’s men ensured a deserved share of the spoils.
That Wednesday came away with a draw was largely down to a brilliant performance from goalkeeper Keiren Westwood, fresh from his player of the month award from September and putting in another star turn which will see him installed as the early favourite for the October prize.
Westwood produced stunning stops to deny Mirco Antenucci and Rodolph Austin among several other important saves.
The Owls were the poorer of the two sides in a goalless first half.
After a bright opening five minutes, Wednesday found themselves struggling for possession and lacking any real cohesion in the opposition half.
Leeds on the other hand looked threatening, particularly on the break while their through balls produced plenty of nervy moments eased only by the offside flag.
Leeds had a free kick in a dangerous area inside the first two minutes but Doncaster-born midfielder Mowatt curled the ball harmlessly wide of Westwood’s near post.
The Owls first chance came in the seventh minute when Maguire’s high ball found Atdhe Nuhiu who put his header well over.
Westwood had to be alert to deny Leeds the opening goal of the Yorkshire derby clash.
The Owls’ keeper raced out to close down Alex Mowatt who had been played into the box by Tommaso Bianchi.
Souleymane Doukara powered to the edge of the box and flashed a shot across the face of goal which beat Westwood but went wide of the far post after 15 minutes.
Westwood produced a brilliant one-handed stop to keep out Austin.
Austin produced a 30-yard thunderbolt but Westwood saved superbly, tipping the ball over the bar.
The hosts did have the ball in the back of the net two minutes from the break only for the flag to deny them once again. Austin released Antenucci into the box and he finished well but was offside.
For all their time on the back foot, Wednesday really should have gone in front a minute from half time. Chris Maguire sent over a fine inswinging cross and Stevie May lost his marker and scuffed a header which went agonisingly wide with Leeds keeper Marco Silvestri left standing.
Leeds started the second half in rampant fashion.
And it took two fine saves from Keiren Westwood to prevent Leeds from taking the lead early in the second half.
First, he rushed out to clear when Souleymane Doukara was played in clear by Alex Mowatt.
And then he produced a fine stop with his legs as Mirco Antenucci was played through as Leeds’ threatening through balls produced another chance.
Sandwiched by Westwood’s two saves was a piece of alert defending from Liam Palmer to keep out Antenucci.
Antenucci lobbed the on-rushing Westwood with Palmer racing in to head the ball off the line.
The hosts’ advances were quelled on 52 minutes when Maguire put the Owls in front.
Jacques Maghoma’s cross was only half cleared out to Maguire who drilled a low shot from 20 yards which nestled in the far corner.
The Owls could easily have doubled their lead on the hour mark. Substitute Gary Madine - on at half time for Atdhe Nuhiu - cut a pass back for Stevie May who turned and sent a low, tame shot wide of the far post.
The game got heated after the Owls took the lead with five yellow cards dished out in a six minute spell.
And just when matters had calmed down, Bellusci equalised for Leeds to set up a tense last ten minutes at Elland Road.
The defender pounced to side foot home on the half volley after Wednesday had failed to clear an Alex Mowatt free kick on 79 minutes.
Leeds had a glorious chance to go in front when Austin brought down a high ball from Mowatt but drilled high and wide from 12 yards out with just three minutes remaining on the clock.
And as the game entered five agonising minutes of stoppage time, Madine did superbly to claim a ball ten yards out and turn only to produce a tame shot which was an easy save for Silvestri.
