Barton threatens action over red card

QPR captain Joey Barton continues to walk a disciplinary tightrope after claiming he could sue over the red card he received against Norwich.

The west London club have appealed to the Football Association against Barton’s dismissal in Monday’s 2-1 home defeat, and it is understood the governing body in turn are to seek observations from Rangers over critical comments from director Ruben Emir Gnanalingam.
