Matt Smith and Ravel Morrison could be in the QPR starting line-up at home to Huddersfield.
The deadline-day signings came on as substitutes during the 1-0 defeat at Blackburn last weekend, while Morrison built up his match fitness further by playing for the under-23s in midweek.
Idrissa Sylla and Yeni Ngbakoto have returned to full training following spells out and could also be involved.
Defender Jack Robinson is still a doubt after a hamstring problem.
Huddersfield will be without forward Kasey Palmer, who has been ruled out for eight weeks due to a hamstring injury.
Palmer, on a season-long loan from Chelsea, was forced out of last Sunday's home win against Leeds midway through the first half.
Midfielder Philip Billing could return to contention after illness but winger Sean Scannell, who has not featured since the end of November, remains sidelined with an ankle injury.
Otherwise, head coach David Wagner has a fully fit squad to choose from, with Nahki Wells, Izzy Brown and Joe Lolley all pushing for recalls to the starting line-up.
