QPR captain Joey Barton claimed on Tuesday he could sue over the red card he received against Norwich.
QPR have confirmed they will appeal to the Football Association against Barton's dismissal in Monday's 2-1 home defeat.
And the 29-year-old former Manchester City and Newcastle midfielder wrote on Twitter on Tuesday: "I wonder how long it is before a football club sues a referee for making a bad decision? There's too much at stake to not have technology."
