The 19-year-old, who is on a three-month youth loan at Wycombe until February 26 has returned to Loftus Road for treatment on a stress fracture in his left foot.
Parker joined the Wanderers last month but has so far only featured once for Gary Waddock's side coming on as a second-half substitute in the 3-1 defeat at Torquay on November 23.
