Bernard Tomic's father has allegedly assaulted a member of his son's support team during a practice session in Europe.

John Tomic - who is also Bernard's coach - reportedly spent one day in jail in Madrid for headbutting a team-member in the face.

Tennis Australia has yet to confirm the reports, which suggest the assaulted man was 29-year-old Thomas Drouet, an inactive French player registered with the ATP World Tour.

Reports in French newspaper L'Equipe suggest John Tomic will face court in the coming days.

Tennis Australia's head of men's tennis Todd Woodbridge said the organisation was still trying to confirm details of the incident.

"We're still trying to ascertain if or what charges have been laid," Woodbridge told 3AW radio.

He said reports that Bernard Tomic faced a potential 12-month suspension were wrong.

"It's totally incorrect because this would have nothing to do with Bernard's behaviour.

"What's important for us at Tennis Australia is that this allegation is thrown toward John, his dad, and not to Bernard."

Tennis journalist Matt Cronin said that he understood Drouet stepped in when Tomic tried to assault his son.

"He broke his nose with a head-butt and knocked him out cold for 20 minutes," Cronin told Fox Sports.

"John will appear in court in Madrid to answer to the charges."
