St George Illawarra is looming as the most likely home for sacked Raiders star Josh Dugan with his father's strong support for the club believed to be a motivating factor.

The Dragons are reportedly still interested in Dugan after failing to secure his signature in 2012 when he opted to re-sign with Canberra for $1.3 million over two years.

It is understood that Dugan's father is a stout Dragons supporter, which could influence the 22-year-old's chances of heading to the club.

The Raiders board voted unanimously to terminate Dugan's contract on Thursday citing repeated breaches of the club's code of conduct, believed to have been sparked by a breakdown in his relationship with coach David Furner.

Dugan was photographed drinking while injured, a breach of club rules, after Canberra's loss to Penrith on Sunday and in the image he was giving a middle-finger salute.

The image, taken and uploaded to a social networking site by Dugan himself, featured teammate Blake Ferguson, who on Thursday was hit with a $10,000 fine and ordered to undergo counselling.

Brisbane, Penrith and the Cowboys all showed a lack of interest in signing Dugan despite early reports linking him to each of the clubs.
