MILLWALL dropped to ninth in the Championship table and lost further ground on the play-off pack after a 2-0 defeat to Burnley at The Den.
Sam Vokes and Danny Ings scored either side of half-time to secure a much-deserved victory for the Clarets, who could have won by a greater margin had they converted a host of other chances.
Kenny Jackett's side, who were second-best throughout, had little to show for their efforts at full-time and will have to improve against Aston Villa in the fourth round of the FA Cup next Friday.
Striker Nathan Tyson, who has signed from Derby County on loan until the end of the season, was named on the bench as boss Jackett stuck with Andy Keogh and Dany N'Guessan up front.
Jack Smith came into the team to replace the suspended Shane Lowry in Millwall's only change from their 1-1 draw with Bolton at the Reebok Stadium last weekend.
In the bitterly cold weather, the Lions were slow out of the traps and Jimmy Abdou made a crucial block in the 13th minute to cut out Dean Marney's cross, with Vokes waiting to pounce.
Millwall carved out their first half-chance when Jack Smith's long ball was headed down by Danny Shittu into the path of N'Guessan, but the striker could only flick the ball behind for a goal kick.
Burnley should have taken the lead in the 16th minute when Vokes forced David Forde into an error and crossed the ball for Ross Walace, who inexplicably scuffed his shot straight at the Lions keeper.
But Sean Dyche's side did not have to wait much longer before going in front. Junior Stanislas intercepted James Henry's pass on the edge of the area and crossed for Vokes, who stabbed the ball between Forde's legs.
With Millwall rocking on their heels, Ings was given time and space on the edge of the area to make it 2-0, but he curled well over the bar.
It was not until the 27th minute that the Lions had their first meaningful effort on goal when Henry took aim from 20-yards-out, but his snapshot brushed the roof of the net.
Henry was growing into the game and it was his deep cross that caused a moment of panic in the Clarets defence in the 34th minute, but Jason Shackell intercepted Martyn Woolford's pass back into the danger zone.
Woolford then turned provider for Liam Trotter, who hooked the winger's cross goalwards, but the ball flew straight into the arms of Burnley 'keeper Lee Grant.
Tyson was introduced at half-time at the expense of Woolford as Jackett sought to breathe fresh energy into his side, who has looked laboured in the opening 45 minutes, and the move nearly paid off.
Millwall should have equalised in the 51st minute when Henry's excellent cross picked out the run of Andy Keogh, but the striker could not adjust his feet in time to steer the ball goalwards and instead bundled wide.
Henry created another opportunity moments later when his first-time delivery narrowly evaded the despairing dives of both N'Guessan and Tyson at the back post.
But Burnley added a decisive second goal just before the hour mark to stifle the Lions' momentum when Ings headed in Trippier's cross after Vokes' near-post flick-on.
Ings should have made it 3-0 in the 70th minute when he brought the ball down down inbetween Mark Beevers and Shittu, but he sliced his shot off target.
Substitute Keith Treacy had an even better chance to add to Millwall's woes when he was played clean through on goal, but Forde made an instinctive one-handed save to keep his shot out.
Jackett's men pushed for a late consolation but the closest they came to doing so was when Trotter's half-volley was blocked on the line by Trippier.
