The 30-year-old has been sidelined with a knee injury since firing the club to a 0-1 victory over Charlton Athletic last month, but has shaken off the knock in time for the clash with Harry Redknapp's men.
Lomas, who faces Redknapp for the first time as manager having spent four years playing under him at West Ham United, has named three other changes from the 5-2 defeat to Bournemouth a fortnight ago.
Shaun Derry - on loan from the West London outfit - is ineligible for the visit of his parent club, as Josh Bailey deputises for the veteran midfielder, while there also starting berths for defenders Paul Connolly, Danny Shittu.
Meanwhile, Redknapp has named two changes from the side which beat Barnsley 2-0 last time out.
Millwall: Forde; Connolly, Robinson, Shittu, Malone; Abdou, Bailey; Waghorn, Trotter, Woolford; McDonald
Queens Park Rangers: Green; Simpson, Dunne, Hill, Assou-Ekotto; Henry, Hoilett, O'Neil, Barton; Kranjcar; Austin
