FA charge Barton
Joey Barton is facing the threat of a 10-match ban - or even longer - after the Football Association charged him with two acts of violent conduct following his sending off in QPR's defeat by Manchester City.
Barton was sent off for elbowing Carlos Tevez and then kicked Sergio Aguero before attempting to headbutt Vincent Kompany.
He will receive an automatic four-match ban as it was his second dismissal of the season, and could receive three-match suspensions for each of the violent conduct charges. On top of that, the FA's regulatory panel will have discretionary powers to increase the length of the suspension if charges are found to be proven.
That leaves the midfielder facing a lengthy suspension at the start of next season - something that could deter interest from other clubs in signing him if QPR decide they wish to part company.
Barton insisted via Twitter that he had not lost his head but that a team-mate "suggested I should try to take 1 of theirs with me".
QPR chairman Tony Fernandes said Barton's future would be reviewed but that the 29-year-old had been an integral part of the club.
"There are experienced people who will come back to me and we'll review the whole situation," he told BBC Sport.
Fernandes highlighted the fact that Djibril Cisse was also sent off twice since in January.
He added: "Joey has been an integral part of the club and has played his part. Cisse has been sent off twice, and I think he was critical for us in terms of getting goals. This is football, and I'm new to it. I don't profess to have all the answers."
Barton denied trying to deflect attention away from his behaviour after launching an expletive-laden attack on Alan Shearer, his former manager at Newcastle and current Match of the Day pundit. Barton said on Twitter: "No deflections here mate. Think the fact about 100m people seen it will see to that. Just don't like how he goes personal...''
