SYDNEY (AP)—News Limited is reporting from Madrid that the court matter involving the father of tennis player Bernard Tomic has been adjourned until October after the man he allegedly assaulted declined to return for Tuesday's scheduled hearing.

John Tomic was charged with assault after allegedly head-butting his son's hitting partner, Thomas Drouet, outside a hotel during the Madrid Open. Drouet said he was left with a broken nose and needed a temporary neck brace.

News Limited newspapers in Australia reported that Drouet couldn't be in Madrid on Tuesday, but didn't offer an explanation. The case will be relisted on a date to be set in October.

John Tomic, who claims he acted in self-defense after being provoked by Drouet, has been barred from attending tennis tournaments while the case is being investigated.
