Sheffield Wednesday's slim chances of avoiding relegation were further hit despite Keiren Westwood's penalty save earning them a point against Nottingham Forest.
The Owls can still preserve their Championship status on goal difference, but need favours from both Derby County and Rotherham United.
Wednesday must hope Derby lose to Swansea City later on Saturday to tee up a must-win game against the Rams on the final day of the season.
But even that may not be good enough if Rotherham, who have a superior goal difference to both Derby and the Owls, pick up four points in their remaining three games.
A Wednesday defeat would have ensured second-tier football next season and Westwood's fine stop from Lewis Grabban's spot-kick late in the first half, after the keeper brought down Anthony Knockaert, could yet prove crucial.
Owls boss Darren Moore picked the team and was heavily involved despite being absent while he recovers from pneumonia which was triggered by contracting Covid-19.
But the hosts were poor before the break and although they improved, they created precious little despite some typically bright moments by Barry Bannan.
Substitute Jordan Rhodes posed problems, while Josh Windass came closest to scoring when a ferocious near-post strike forced a fine save from Brice Samba.
Forest, who are 16th in the table, also only rarely threatened, with a James Garner miskick and Grabban's effort into the side netting as good as it got.
The first half was flat, tedious and cautious, with only a tame effort on goal by Wednesday's Kadeem Harris sparking interest until a dramatic finish.
Moments after Filip Krovinovic wasted a good shooting opportunity for Forest, the Owls got in a mess playing from the back when Westwood's sliced clearance was met with an even worse headed back pass by Adam Reach but the keeper made amends.
