Wales will not play again before their World Cup campaign starts in November.
Rob Page's men were beaten 1-0 by Poland at Cardiff City Stadium in the Nations League on Sunday night in what is their final fixture before the global showpiece in Qatar.
The Red Dragons tentatively explored the option of having a warm-up fixture prior to their World Cup opener against the United States of America on November 21, although the lack of preparation time between that contest and the beginning of the domestic season break ensured it was not possible to play a friendly game.
