Here is a look at how the two teams line-up:
Millwall: Forde; Edwards, Dunne (C), Beevers, Malone; Abdou, Williams; Martin, McDonald, Woolford; Fuller.
Subs: Bywater, Webster, Briggs, Wright, Easter, Gueye, Gregory.
Leeds United: Silvestri, Byram, Pearce (C), Wootton, Warnock, Austin, Murphy, Tonge, Ajose, Hunt, Doukara.
Subs: S Taylor, Killock, Berardi, Cook, Benedicic, Smith, Poleon.
It has been a typically chaotic summer for Leeds United.
They are, however, ready to kick off a new season with all their limbs in tact - so to speak.
Dave Hockaday will take charge of his first Championship game and sees his squad travel to face Ian Holloway's Millwall.
This time last season, Holloway was looking ahead to life in the Premier League with his newly promoted Crystal Palace side. Now, he is just across south London at the Den.
He has named new striker Ricardo Fuller in his starting line-up for the Championship clash.
