Gold Coast says any decision over Campbell Brown’s AFL future won’t be made until an investigation into an incident with teammate Steven May is completed.

Brown’s future with the Suns appears all but over after he allegedly punched May during an altercation at a Los Angeles nightclub following a pre-season training camp in the United States.

May is reportedly set to go into hospital on Friday to undergo surgery on a broken jaw.

Suns chief executive Travis Auld told reporters on Friday no decision has been made on what action will be taken against the former Hawthorn premiership player.

Speculation has been rife as to the cause of the incident, with a disputed bar bill, personal insults and even an attempt by May to re-enter the nightclub to get an autograph from pop star Rhianna among the reasons reported.

But Auld said the exact details are still unclear.

“All we know at the moment is they were both drinking, something has flared up and Steve May has a broken jaw,” News Limited reports Auld saying.

Up to five other players are believed to have seen the incident and will be spoken to by the club as part of the investigation.

It’s far from the first time the 205-game Brown has been involved in an off-field incident, with the ex-Hawk having being stripped of a leadership role at the Suns last year after being detained by police in Thailand.  

He has also missed 28 games through suspension during his career, including the first six rounds of the 2013 campaign.

A current suspension will also mean Brown misses the opening match of the 2014 season.

Brown, who has been barred from training until the matter is resolved, went to ground following his return to Australia on Thursday.

He told the Gold Coast Bulletin he was “letting the club sort it out” but refused to elaborate on the details of the incident.
