Adelaide United and police are still hunting a fan who racially abused Wellington star Paul Ifill during Sunday's A-League match in Adelaide.
Ifill, an English-born Barbados international, says he was racially vilified by a minority of the Hindmarsh Stadium crowd during his club's 3-1 loss.
Adelaide captain Eugene Galekovic says the abuse shouldn't be tolerated.
"I don't condone racial sledges or anything like that but I don't know what was said so I will leave it up to the club," Galekovic told reporters in Adelaide on Monday.
"Racial abuse is something different ... society these days, there is a line and you can't really cross that line anymore."
Adelaide and Football Federation Australia (FFA) were investigating the incident after Wellington Phoenix lodged a complaint.
A Phoenix spokesman said on Monday the club would make no further comment on the issue after Adelaide called in police.
Ifill confirmed he was racially abused on Sunday night.
"Bad times poor result and racist abuse from a very small minority of fans #nothappy," he posted on Twitter.
"... It was a small minority no problem with a bit of banter but a line was crossed today."
Ifill, among the A-League's elite players, was believed to have been repeatedly called a racially-derogatory term when substituted during the game.
An Adelaide United spokesman said on Monday the club was still searching for the fan or fans who taunted Ifill.
The 33-year-old Ifill was born in Brighton in England and played 238 games for English club Millwall, including the 2004 FA Cup final against Manchester United, and also had stints at Sheffield United and Crystal Palace before joining the Phoenix.
