Wales face the Proteas in a one-off Test in the United States before coming up against the Pumas twice, but Jones looks set to be given a rest.
"I don't think he will go on tour in the summer," Wales head coach Gatland said after his side's Six Nations win over France.
"It is about us managing him over the next 18 months.
"We have got a plan in place for him over the next year or so in terms of the amount of games he plays for the Ospreys and for us.
"He is very important for us and we need to keep him fresh."
