The father of Australian tennis player Bernard Tomic has been suspended from the ATP tour until further notice following an alleged assault on his son's training partner.
John Tomic appeared in a Madrid court on Monday after being accused of headbutting his son's French training partner Thomas Drouet.
He denied the charge, saying he acted in self defence and will return to court on May 14 for a judge to decide his guilt or innocence.
Bernard Tomic is competing in Italy at the Rome Masters next week but, as it stands, his father and coach will not be allowed to attend.
"Following last week's incident in Madrid concerning John Tomic, and the ensuing investigation, Mr Tomic's credential privileges have been suspended at all ATP tournaments until further notice,'' the ATP told AAP in a statement on Tuesday.
