Wales will discover on Tuesday whether their opening European Qualifier can be played in Andorra on 9 September.
Last Friday UEFA announced that more work needed to be done on the new artificial 3G surface at the national stadium in Andorra la Vella.
Tests on Thursday showed the ball was rolling too fast on the surface and if Andorra cannot rectify the problem then the match will be moved to another country.
The Football Association of Wales confirmed they expect an answer on the situation in the next 24 hours.
"UEFA has today informed the Football Association of Wales that a further pitch inspection will today be carried out on the new 3G surface at the Andorra National Stadium," a statement from the FAW read.
"UEFA believe that if the necessary work has been carried out over the weekend, the game will be played at the stadium.
"A decision will be made within the next 24 hours."
Winger Hal Robson-Kanu, meanwhile, became the second player to withdraw from the Wales squad on Monday following West Ham defender James Collins.
Robson-Kanu has not played since suffering a knee injury in a pre-season friendly in July and has been replaced by his uncapped Reading team-mate Jake Taylor.
