Hart, looking for his first win since taking over at Rangers, will be able to include the duo on Boxing Day after they returned from knee and pelvic injuries, respectively.
However, QPR will be without Jamaican centre-back Damion Stewart through suspension.
Stewart picked up his fifth booking of the season in last weekend's 1-1 draw with Sheffield United and therefore incurred a one-match ban.
Hart will also be without several long-term absentees.
Gavin Mahon, Lee Cook and Martin Rowlands are all out with various knee complaints, while Gareth Ainsworth is ruled out for five weeks with a calf injury.
