Newcastle United midfielder Joey Barton has been handed a 12-match ban, six of which are suspended, for assaulting former team-mate Ousmane Dabo.
The controversial midfielder faced a Football Association regulatory commission on Friday after pleading guilty to a misconduct charge which dated back to his time as a Manchester City player.
Barton was given a four-month suspended sentence by Manchester Crown Court in July after pleading guilty to assaulting Dabo at his former club's training ground on May 1 2007.
The 25-year-old was released from prison on July 28 after serving two months of a six-month sentence for a separate assault in Liverpool city centre at the end of last year.
The six-match punishment will begin with immediate effect and Barton was also fined £25,000 by the FA.
However, the regulatory commission were swift to warn the troubled midfielder that the suspended six games of the punishment will come into effect 'should Barton be found guilty of any similar charge involving violence or be dismissed from the field of play for violent conduct'.
"The commission members considered principally the serious attack by Mr Barton that clearly cannot be accepted," said chairman Maurice Armstrong.
"The members also had to take into consideration the sanctions imposed by the courts and the pro-active support Mr Barton has received from Newcastle United and other professional bodies.
"The commission members wanted to punish the offence appropriately but give Mr Barton an opportunity to ensure his professional conduct does not falter again and ensure he is fully aware of the consequences should he make another serious error of judgement."
