ANDY Keogh returned to haunt his former club with the winning goal as Millwall's incredible run of form continued against Wolves.
The Lions are now 12-games unbeaten and climbed up to fifth in the Championship table after Keogh's 78th-minute strike settled an otherwise uneventful affair at Molineux.
With James Henry serving a one-match suspension, Kenny Jackett was forced to make one change to his side, drafting in Liam Feeney on the right side of midfield.
Young forward Aiden O'Brien was named as a substitute for the first time this season, having made his debut for the club in a 5-0 League Cup defeat against Wolves last term.
The Lions were slow out of the traps on a bitterly cold evening in the Black County and Kevin Doyle and Bakary Sako had quick-fire efforts blocked by Mark Beevers in just the second minute.
The home side had a strong appeal for a penalty waived away when Danny Shittu barged Doyle to the ground, but referee Michael Naylor adjudged the challenge had been outside the area.
In the 13th minute, striker Bjorn Sigurdarson found himself unmarked on the edge of the area but glanced a header well over from Sako's inswinging free-kick.
Despite struggling to create genuine goalscoring opportunities, the best chance of the first-half arguably fell to the visitors when Chris Wood broke clear, but he delayed his shot and Christophe Berra nicked the ball off his toes.
Sako was proving to be Wolves' dangerman and Doyle was inches away from converting his venomous low cross in the 26th minute, before Adam Smith drilled into the side netting at the other end.
Millwall came out for the second-half with renewed vigour and after Taylor had sliced a shot well wide, Keogh drilled straight into the hands of Carl Ikeme after Wright's quick free-kick into the channel.
Chances remained at a premium and both Feeney and David Edwards blasted efforts over from the edge of the area for either side as the game appeared to be petering out into a bore draw.
But out of nothing, the deadlock was broken. After substitute Dany N'Guessan's shot took a fortuitous deflection, Wood held the ball up and played the perfect pass for strikepartner Keogh, who slammed home from eight yards.
Wolves spurned a golden chance to equalise when Sako's loss cross was inexplicably bundled wide by Sylvan Ebanks-Blake, who then miscued an effort well over from the edge of the box.
