Charlie Austin could make his first league start on Saturday after scoring the opener on his full debut at Exeter. If Redknapp does select the former Burnley man, then one of either Bobby Zamora or Andy Johnson might have to sit out.
Huddersfield also progressed in the League Cup, knocking out last year's finalists and West Yorkshire neighbours Bradford.
The Terriers' league campaign didn't begin in winning fashion though as they were edged out by Nottingham Forest on Saturday.
The last time these two faced each other was more than 10 years ago in the old Division Two. That day QPR won 3-0 thanks to a Paul Furlong brace and Danny Shittu's close-range effort.
Possible starting lineups:
Huddersfield: Smithies; Hunt, Clarke, Lynch, Dixon; Gobern, Hogg; Hammill, Clayton, Scannell; Vaughan
QPR: Green; Simpson, Onuoha, Dunne, Traore; Faurlin, Barton, Henry, Hoilett; Johnson, Austin
Sports Mole says: 0-2
