It is a reward for his fine start to the season under Steven Gerrard at Rangers, where he has scored six goals in 11 appearances.
He has previously played for the u20 side, but this will be his first experience in the senior setup.
Radamel Falcao currently captains the side and Morelos will get the chance to ply his trade with other stars, although James Rodriguez has been left out of this squad.
The 'Cafeteros' will play two friendlies in the USA, against Argentina in New Jersey after a clash with Venezuela in Miami.
