James Rodriguez and Yerry Mina have been left out of the Colombia squad for next month's international matches with Venezuela and Argentina.
Bayern Munich star James has been omitted to allow him to continue his recovery from an injury sustained at the World Cup.
Mina, meanwhile, is yet to make an appearance for Everton since joining from Barcelona this month.
"It was agreed that this was not his [James'] call-up," explained Arturo Reyes, who is in temporary charge of Colombia's senior side while Jose Pekerman seeks to resolve a dispute with the football federation.
"Next month he will certainly be there, but the most important thing for now is that he completes his recovery process and gets back into matches progressively."
Rangers striker Alfredo Morelos has been called up for the first time, while Valencia's Jeison Murillo is back after being left out for much of the last two years.
Colombia face Venezuela in their first post-World Cup friendly on September 7, before facing Argentina four days later.
