TWO goals in ten first-half minutes saw Bournemouth cement top spot in the Championship and heap more misery on struggling Millwall.
The Lions never looked like bouncing back after the Cherries took the lead through Yann Kermorgant's 32nd minute penalty, awarded after Lee Martin's trip on Charlie Daniels.
The visitors doubled their lead before the break when Callum Wilson beat the offside trap and squared for Harry Arter, who finished smartly into the corner.
Bournemouth had chances to extend their lead in the second half, with substitute Dan Gosling firing narrowly wide.
Millwall's afternoon went from bad to worse late on when Shaun Williams lashed out at Wilson and was shown a straight red card by referee David Coote.
Defeat was the Lions' third in a row and fourth on the spin at The Den.
Ian Holloway rung the changes after Millwall were thrashed 6-1 by Norwich City on Boxing Day, with seven new players coming into the starting XI.
Among them was academy graduate Sid Nelson, who made his first senior appearance for the Lions at centre back.
Scott Malone, Andy Wilkinson, Jimmy Abdou, Scott McDonald, Lee Gregory and Martin also returned to the starting XI.
Bournemouth, who arrived in SE16 on the back of 13-game unbeaten run, had the first chance when Kermorgant's free kick was pushed away by David Forde.
At the other end, Nelson headed wide from Martin's set piece and Tommy Elphick intercepted Malone's cross before it reached Gregory.
By the half-hour mark, there was little to separate the two sides and Millwall were doing well to disrupt the Cherries' passing football.
But an overzealous challenge by Martin on Daniels handed Bournemouth the chance to take the lead from the penalty spot.
Martin claimed that his foul was committed just outside of the area but his protests fell on deaf ears as Kermorgant converted from 12 yards.
And when Danny Shittu played Wilson onside, the former Coventry City striker picked out Arter who jinked into a yard of space before slotting in the second goal.
At half time, Holloway brought on Ricardo Fuller for Andy Wilkinson and went with two up front – just as he had done at Dean Court in the reverse fixture last month.
A comeback could have been on the cards had Abdou's chipped cross found Gregory but the ball curled inches beyond the forward's dive at the far post.
Bournemouth managed the game well and Gosling could have scored a third, only to fire wide when well-placed inside the area.
And the Lions' frustration boiled over in the closing minutes when Williams stamped on Wilson and was immediately given his marching orders.
