WALLABIES winger Digby Ioane will report to Victorian Police on Tuesday to seek a revised court date to answer a summons for an alleged assault.

The Wallabies were caught unawares by a warrant on Monday afternoon for the arrest of winger Ioane which was issued for his failure to appear in a Melbourne court on the same day as a training session across town.

A magistrate issued the warrant when Ioane did not appear in the Melbourne Magistrates Court today to answer a charge of unlawful assault stemming from a pub drama in the Melbourne suburb of Prahran on March 9.

The Australian Rugby Union was blindsided by the incident and a frantic round of phone calls tried to get to the bottom of the incident.

In a prepared statement the ARU said: "The ARU was only made aware late this afternoon of the issue involving Digby Ioane.

"Since being made aware through media reports, ARU has worked expeditiously with Digby Ioane and Victorian Police to attend to this matter.

"Digby will report to Victorian Police and will be issued with a revised court date."

The Ioane summons was issued on the Queensland Rugby Union's watch.

Sources indicate the Ioane summons might not simply have been passed along the correct chain of command and not diarised by Ioane.

Ioane was in a Melbourne pub the day after the Queensland Reds' win over the Melbourne Rebels when he was involved on the fringes of an incident involving his brother.

Police investigated Ioane's 30-year-old brother becoming involved in a verbal altercation with a Prahran man of the same age. It was alleged the Prahran man sustained a minor leg injury.

Ioane, the 35-Test winger, is carrying a shoulder injury from last Saturday's Test loss to the British and Irish Lions and is unlikely to play in Saturday's second Test in Melbourne.

He was on the sidelines watching his teammates train at the Carlton Football Club's Visy Park ground today when the first report of the arrest warrant was made public just after 4pm.
