Sheffield Wednesday moved a step closer to relegation from the Championship after falling to defeat at Middlesbrough.
Boro went in front when Owls centre-half Julian Borner coughed up possession to Yannick Bolasie, whose shot deflected off Tom Lees past goalkeeper Keiran Westwood.
Josh Windass levelled with a clinical penalty when Marc Bola was adjudged to have tripped Andre Green after a silky run into the box.
Josh Coburn's towering header put the hosts back in front before Duncan Watmore scrambled in a third from Paddy McNair's corner.
A 16th away defeat of the season, combined with Derby's home defeat by Birmingham, left second-bottom Wednesday four points from safety with two games remaining, while back-to-back wins lifted Boro to ninth.
