QPR skipper Joey Barton has hit back at Norwich City midfielder Bradley Johnson as their red card row continues.

Johnson was pictured at the PDC World Darts Championship final on Monday night with a placard mocking the QPR captain. It read: "Barton, your breath stinks."

Barton responded in kind on Tuesday, as he said on Twitter: "Don't worry people I've seen Boris [sic] Johnson from Norwich with his sign at the darts. He's irrelevant really, absolute no mark."
