Neil Harris has made two changes as Millwall look to upset the odds against promotion-chasing Sheffield United at Bramall Lane.
Murray Wallace and Tom Bradshaw both remain sidelined with long-term problems, whilst Jordan Archer (leg) and Shaun Hutchinson (illness) continue to miss out.
But Shane Ferguson is available after a three-match suspension and comes straight back into the side at left-wing-back as Harris opts for three-at-the-back.
