Dwight Yorke has threatened to quit the Trinidad and Tobago team unless he is allowed to play in Saturday's World Cup qualifier against Honduras.
The local soccer federation dropped Yorke from the roster for the qualifier after the striker failed to show for an away friendly match against Panama.
Yorke's local agent Tim Nafzigger says the Manchester United star will not train until the decision is reversed.
Yorke had appealed, but team technical director Rene Simoes stood by the suspension.
"While Yorke hasn't as yet made up his mind on retirement from international football, he cannot accept the decision taken by the technical committee and will not train until the decision is reversed," said Mr Nafzigger.
Under the suspension, Yorke is still be eligible to play away against the United States on June 20 in Foxboro, Massachusetts, and until Thursday he was training with the team.
Nafzigger says he is still working to convince Simoes and Trinidad and Tobago Football Federation President Oliver Camps to reverse the suspension on Yorke for the Honduras game.
Yorke missed the Panama game only because he missed his plane connection in Miami, and was then forced to return immediately to England to be with an ill sister, Nafzigger said.
Anthony Rougier, of England's first division team Reading, was also dropped from the roster. He also did not make himself available for the Panama game.
Trinidad must win Saturday's game against Honduras to have a real chance in the six team round-robin final qualifying in the CONCACAF group. The team is in last place with only one point after three games, having tied Mexico in Port-of-Spain.
