|Smith 19, McCormack 41||Venue: Elland Road
A POOR defensive showing in the first half cost Millwall a point at Elland Road.
After a bright opening, the Lions fell behind when Matt Smith's improbable header looped over David Forde in the 19th minute.
And the visitors' back four seemed half asleep as Ross McCormack pounced on a ricochet and stabbed a shot under Forde from close range.
Substitute DJ Campbell's stunning 25-yard half-volley reduced the deficit but could not inspire the equaliser that Millwall's play between the two penalty areas deserved.
Ian Holloway made three changes to the side that drew 0-0 with Charlton as John Marquis, Scott McDonald and Mark Beevers all came into the starting XI.
Steve Morison (ineligible) and Shaun Williams (banned) were missing, while Simeon Jackson dropped to the bench. DJ Campbell returned to the squad after a hamstring injury.
McDonald was the architect of the game's first chance in the fourth minute, feeding the ball wide to Marquis but the striker's shot was blocked.
90 seconds later, Ed Upson's cross from a free kick eluded everyone in the penalty area except for goalkeeper Jack Butland, who tipped the ball around the post at the last second.
Upson then skipped past a tackle on the edge of the area and delivered a low cross into the box but Tom Lees prevented Fred Onyedinma from turning a shot home.
Millwall's good start to the game continued as McDonald exchanged passes with Onyedinma before teeing up Marquis, but the home side scrambled the ball behind for a corner.
And Leeds took the lead against the run of play in the 19th minute when Smith's powerful header from Connor Wickham's long throw dropped over Forde and into the net.
Alan Dunne produced a vital near-post interception to prevent McCormack making it 2-0 before Martyn Woolford's drive was held by Butland at the other end.
But McCormack did add a second goal for the hosts in the 41st minute when Lees' tackle on Marquis fell kindly for the Scotland international, who poked between Forde's legs.
Millwall created the first opening of the second half when McDonald's pass picked out the overlapping run of Beevers, who forced a diving save from Butland.
The Lions should have pulled a goal back in the 50th minute when Marquis teed up McDonlad, but a combination of Butland and defenders kept the Australian's shot out.
That miss prompted Holloway to use all three of his substitutions in quick succession as he brought on Campbell, Simeon Jackson and Stefan Maierhofer.
And it was two of the new introductions who combined to halve Leeds' advantage in the 73rd minute.
Maierhofer chested a long ball into the path of Campbell and the striker barely broke stride as he hammered a sweet half-volley into the top corner from the edge of the area.
Butland then denied Maierhofer from close range before Woolford and Jackson both had efforts blocked following a chaotic goal-mouth scramble.
McDonald's ambitious 30 yarder, which sailed over, was the Lions' last effort of note as Leeds held on to win 2-1.
