Davidson AWOL from Heracles training camp
The West Bromwich Albion target has been locked in a dispute with the Eredivisie club which claims he is contracted to them for another year.
The 23-year-old, who was part of Australia’s World Cup squad, is one of a number of Socceroos hoping to secure post-Brazil transfers.
Heracles club chairman Jan Smit told Voetbal International: “Since Monday he has not reported here, Jason has not fulfilled his obligations.
“What I understand, he is in England looking for a new club. Perhaps that provides a solution. "
Smit added: "Meanwhile, we are working to effect a settlement with his agent. Then you have to think of financial compensation and another left back."
