Boxing great Joe Calzaghe is facing a high court action from his former promoter Frank Warren.
The pair parted company in June, ending a 12-year partnership, and reports suggest Warren is taking the Welsh boxer to court over an alleged breach of contract.
The BBC claims the legal claim was lodged via Warren's Sports Network company, just three days after Calzaghe announced he would promote his next fight on his own.
Calzaghe had been due to fight against Roy Jones JR in New York in September, but the fight had to be postponed this week after the Welshman injured his right hand in training.
The super-middleweight and light-heavyweight champion will now have to wait till November to fight Jones, with the 8th suggested as a possible date for the bout.
Calzaghe, the BBC sports personality of the year, is unbeaten in his professional boxing career and after beating former champion Bernard Hopkins in April this year claimed he would fight once more before retiring.
Neither Calzaghe nor Warren have commented on the alleged legal action.
