The match will be the first time Blues captain John Terry and Hoops defender Anton Ferdinand have faced each other since the Blues' 1-0 defeat in October.
Terry has been charged with racially abusing Ferdinand during the game and will appear in court on February 1. He has denied the charge.
Bruce Buck, chairman of Chelsea, and Tony Fernandes, his QPR counterpart, released a joint statement on Wednesday to show a united front ahead of the tie and asked for the game to be a "celebration of football".
Chelsea and QPR warned supporters that "abuse and discrimination has no place in football or society" and the latter have again reiterated that stance today.
In a post on their official website the club said: "Queens Park Rangers Football Club is committed to confronting and eliminating discrimination, whether by reason of race, colour, sex, sexual orientation, marital status, age, ethnic and national origin, disability, nationality, religion or belief or gender reassignment.
