Leeds will be hoping to overcome a 1-0 deficit from the first leg when the teams meet on Thursday evening.
Millwall have the slender advantage after Neil Harris scored a 71st minute winner in a fairly even first leg.
Leeds history in the second leg of Play off semi finals.
This is the first time Leeds has ever played a home second leg in the Play off semi finals.
In 1987 they travelled to Oldham and lost 2-1 after extra time but having won the home leg 1-0 went through on the away goal rule.
In 2006 they won 2-0 at Preston North End thanks to goals from Rob Hulse and Frazer Richardson to take the tie 3-1 on aggregate.
Last year they won 2-0 at Carlisle United thanks to local boy Jon Howson`s brace, the winner and decisive goal coming in injury time to take Leeds through 3-2 on aggregate.
