Jason Davidson's proposed move to join Adam Taggart at Fulham appears to be off, with Heracles claiming to have triggered an automatic extension to the player's contract.
The left-back, who played all three matches for the Socceroos at the World Cup last month, had been tipped to swap the Eredivisie for England's Championship.
But the 23-year-old is now set to stay at the Polman Stadion for at least the next 12 months, unless an agreement on a transfer fee can be reached with any potential suitors.
"In January, Jason and his agent indicated they would like to continue here for two more years," director of football Nico-Jan Hoogma was quoted as telling Dutch reporters by FourFourTwo.
"He wanted to wait until the World Cup with Australia to decide but because we wanted to keep him we haven't terminated his contract.
"The fact he hasn't left (by July 1) means he is under the same conditions. Those are the rules of the collective agreement for professional footballers and we've discussed this with Jason and his agent."
Davidson began his career with Hume City in the Victorian Premier League before joining Portuguese side Pacos de Ferreira in 2009.
