QPR are hoping to welcome back Tommy Smith and Heidar Helguson for the top-of-the-table clash.
Smith missed last Friday's win over Reading with a hamstring problem and Helguson has been struggling with a groin injury, but Neil Warnock expects the key duo to be fit in time for the televised showdown.
Warnock will, however, be without Hogan Ephraim, who starts a three-match ban following his dismissal at the Madejski Stadium.
Fellow winger Wayne Routledge, who hit the winner against the Royals, should play despite needing a course of antibiotics for an abscess on his tooth.
Midfielder Akos Buzsaky played for the reserves this week after four months out with a knee injury but will not be rushed back.
Nottingham Forest have no new problems ahead of the game.
Billy Davies, manager of the month for January, will select from the same set of players that won for a seventh successive league game against Watford last weekend but may make changes to his starting XI.
Most of Davies' options are attacking, with Nathan Tyson, Lewis McGugan, Dele Adebola, Garath McCleary and David McGoldrick all available for recalls.
Joel Lynch is also ready to return should Davies wish to alter things in defence.
Midfielder Guy Moussi is still nursing the thigh problem that ruled him out against Watford, while January signing Robbie Findley must continue to wait for his debut due to a thigh injury.
