Defender Raldes is one of several senior players left out after a 1-0 home loss to Venezuela and a 4-0 defeat away to Chile in June left Bolivia with virtually no chance of a place at the 2010 finals in South Africa.
Bolivia, who visit Paraguay in Asuncion on September 5 and host Ecuador four days later in La Paz, are one from bottom of the 10-nation South American group with four matches to go.
The top four qualify for the finals while the fifth-placed team goes into a playoff with a team from the CONCACAF region. Bolivia, with 12 points, are eight adrift of Ecuador, the team currently in fifth.
