Match ends, Luton Town 3, Sheffield Wednesday 2.
Elijah Adebayo capped a second-half rally with a late winner as Luton came from 2-0 down to beat Sheffield Wednesday.
Josh Windass' first-half double gave Wednesday a comfortable half-time lead, but Luton manager Nathan Jones made a triple substitution at the break.
The move was soon rewarded as Kal Naismith flicked in Kiernan Dewsbury-Hall's corner before Adebayo's low cross was powered home by Ryan Tunnicliffe to bring Luton level.
Adebayo then completed the comeback, heading home Harry Cornick's cross at the far post, as Luton saw out seven minutes of stoppage time.
Callum Paterson was played into the right-hand side of the area and his low cross found Windass' run to the near post to turn home from inside the six-yard box for his fifth goal of the season to give the Owls the perfect start.
A high cross from the right-hand touchline was then allowed to bounce twice and sat up kindly for Windass to run onto and blast in with his right boot.
But the game turned after Jones rang the changes at half-time, and the Hatters were back in the game within five minutes through Naismith's first goal since joining the club from Wigan in January.
And after Tunnicliffe's quick equaliser another transfer-window signing won it for the home side.
Adebayo was signed from Walsall for an undisclosed fee on deadline day and his winning goal handed Luton just a second win in eight Championship matches.
The Hatters sit 14th, while Wednesday are six points from safety in 23rd after Birmingham's comeback win against QPR.
Luton's Ryan Tunnicliffe told BBC Three Counties:
"Everyone was embarrassed at half-time, but a few of the lads spoke up and the gaffer left us to it - the boys said what needed to be said.
"We've not been playing badly but haven't been picking up the points we like, but to come back like that shows real character.
"Before we left the dressing room we said 'let's get the first goal' and thankfully we did and then pushed on for the win."
Sheffield Wednesday caretaker manager Neil Thompson told BBC Radio Sheffield:
"We just went into our shells and they did to us in the second half what we did to them in the first half.
"It's a tough one to take because the first half was as good as we've played all season and probably half-time came too early for us.
"Second half we just sacked off the game, it was scrappy, we had stoppages and they upped their tempo a hell of a lot."
