Leeds manager Simon Grayson could hand a debut to new signing Mike Grella for the visit of Millwall on Monday night.

The American striker penned an 18-month contract on deadline day following an impressive trial spell at Elland Road, which included a hat-trick against Barnsley during his first reserve-team appearance.

Richard Naylor is likely to continue in the heart of defence after making his loan move from Ipswich permanent earlier this week.

Fabian Delph was not snapped up by another club before Monday's transfer deadline, so the highly-rated midfielder is again available for selection.

Captain Frazer Richardson is expected to spend a further week on the sidelines with the thigh injury he sustained at Brighton last month, so Andrew Hughes is likely to continue at full-back.

Millwall will be without Paul Robinson and Lewis Grabban.

Lions skipper Robinson broke a bone in his foot during the defeat by Scunthorpe last week and is facing around two months on the sidelines.

Zak Whitbread is his likely replacement at centre-half, although boss Kenny Jackett also brought in Richard Duffy on loan from Portsmouth on deadline day and he will be added to the squad.

Grabban is in the treatment room after pulling his hamstring against Scunthorpe so Chris Hackett should start on the wing.

Midfielder Danny Spiller (hip) and full-backs Marcus Bignot and Danny Senda (both knee) remain on the long-term casualty list, while striker Adrian Forbes has joined Grimsby on loan.
