Gold Coast coach Damien Hardwick has been put on notice and the Suns face a potentially costly AFL tribunal case in the fallout from their latest loss.
Friday night's away loss to Geelong is the third straight defeat for the slumping Suns.
Hardwick was fuming post-match and took aim at the umpires, claiming they were influenced by the crowd and the "Roman Colosseum" atmosphere at GMHBA Stadium.
