|Abdou 2||Venue: The Den
|Llera 40, Maguire 90|
CHRIS Maguire stepped off the bench to snatch a stoppage-time winner for Sheffield Wednesday as Millwall's miserable run of home form continued.
Midfielder Jimmy Abdou tapped in his first-ever goal at The Den in just the 2nd minute of the match but his effort was cancelled out by former Charlton defender Miguel Llera's free-kick.
And Maguire hooked in Danny Pugh's near-post corner deep into four minutes of additional time to stun the home crowd in South London, who had watched their side dominate the second-half.
Kenny Jackett handed Chelsea loanee George Saville his first senior start on the left side of midfield, while Jermaine Easter and Abdou were both recalled to Millwall's starting line-up.
Winger James Henry was passed fit to be included amongst the substitutes after a knee injury but Liam Trotter was absent from the squad with a minor muscle strain.
The Lions took the lead with just 63 seconds on the clock when Chris Taylor beat two men down the right wing before sending in a low cross which Abdou, arriving from deep, bundled in.
After Owls left-back Danny Pugh had curled a free-kick over, Rob Hulse could have made it 2-0 when Mark Beevers' clearance fell to him 12-yards out but Chris Kirland smothered the ball at his feet.
Shane Lowry then had two shots on goal in quick succession, first drilling narrowly wide in the 17th minute before lofting a tame set-piece straight into Kirkland's midriff.
David Forde had to stand firm at his near post to keep out Steve Howard's stinging effort and ex-Wednesday defender Mark Beevers headed into the side nettings as the sides traded chances.
But the visitors levelled in the 40th minute when Llera, who scored two goals in the reverse fixture in August, arced a free-kick around the wall and beyond the dive of Forde to make it 1-1.
Taylor went close to restoring Millwall's lead when he got a toe to Lowry's driven cross, but the ball ricocheted straight to Kirkland, who would have been beaten had it gone either side of him.
Jackett's side made a purposeful start to the second period and Easter spurned a half-chance when Beevers' knock-down dropped kindly for him in the 55th minute, scuffing a shot a yard wide.
Shaun Batt and Henry were introduced from the bench and the latter nearly made an immediate impact, threading an inch-perfect bass through for Easter, who drilled at the feet of Kirkland.
Kirkland came to the Owls rescue again in the 62nd minute when he parried Taylor's curler away from danger and made another crucial block to beat away Sean St Ledger's overhead kick.
The Lions were piling on the pressure entering the final 15 minutes of the match but were nearly hit by a sucker punch when sub Jermaine Johnson lashed a shot inches wide after a quick break.
But Wednesday were not to be denied a smash-and-grab victory and Maguire produced the perfect finish to Pugh's driven cross to break Millwall hearts at the death.
