The bad blood between Port Adelaide and the Gold Coast is flowing again with the two clubs having resurrected their dispute over the Suns' choice of jumper for next year's AFL clash in Shanghai.

Barely a month after league chief Gillon McLachlan was forced to act as mediator between club presidents David Koch and Tony Cochrane over coach Ken Hinkley, the pair cannot agree on a series of issues surrounding the 2018 international home-and-away game.

Fairfax Media understands the game has been earmarked as a twilight clash to be played on Saturday, May 12, and broadcast on Saturday night Eastern Standard Time.

But Port, which had pushed to play a Melbourne or Sydney-based team, are playing hard ball over money and the jumper issue.
