SWANS officials have cleared midfielder Isaac Heeney of any wrongdoing after it emerged he was at a Sydney nightspot last weekend when North Melbourne's Taylor Garner allegedly assaulted a man.

Garner, who was staying in the Harbour City with Swans onballer and former Kangas teammate Ryan Clarke while North had their mid-season bye, is alleged to have broken a man's nose at a popular pub in Sydney's eastern suburbs.

The forward has been demoted to the VFL this weekend, with the matter still being investigated by NSW police and the club.

Clarke, who crossed to Sydney in the off-season after three seasons at North, was at the pub with Garner after helping Sydney to a 19-point win over Hawthorn at the SCG the previous evening.

Heeney was also at the venue with a separate group of friends and arrived later in the night.

Swans officials said in a statement that while Heeney witnessed the alleged scuffle, Clarke had already left by the time it occurred.

Sydney footy boss Charlie Gardiner said Heeney stopped the incident from escalating further and lent his assistance to the other man involved.

"Both Isaac and Ryan kept the club fully informed about what occurred over the weekend," Gardiner said.

"Isaac should be commended for diffusing the situation and offering support to the other party.

"As this matter is still being investigated, we are unable to make further comment."

The revelations are an unwanted distraction for the Swans players involved, ahead of their clash with Gold Coast at the SCG on Saturday.
