Newcastle United midfielder Joey Barton has been handed a four-month suspended sentence for assaulting former team-mate Ousmane Dabo.
Barton was due to stand trial at Manchester's Minshull Street Crown Court on Monday over the incident that occurred on May 1 last year when both players were still with Manchester City.
The 25-year-old, who left the Citizens for Newcastle United in a £6million deal last summer, had denied inflicting actual bodily harm on the Frenchman.
However, he changed his plea shortly before the scheduled start of the trial and admitted one charge of assault occasioning actual bodily harm to Dabo.
Barton's career has been littered with disciplinary problems.
In May, he was jailed for six months after admitting charges of assault and affray following an incident the previous December in Liverpool city centre.
In December 2004 he stubbed out a lit cigar in Jamie Tandy's eye during a Christmas party after he had caught the youth team player attempting to set fire to his shirt.
Barton subsequently apologised for his actions and was fined six weeks' wages but the following summer was sent home from a pre-season tournament in Thailand after assaulting a 15-year-old Everton supporter.
