But there was no place for captain Bryan Ruiz, who paid the price for a lack of recent playing time with Brazil's Santos.
"Bryan is aware that he is not playing and that means he doesn't have rhythm," Gonzalez told a news conference.
"We hope that in December he will fix this situation and again be considered for future squads. He is a valuable player, the captain of the national team."
Costa Rica will play Haiti in Bahamas on October 10 before hosting Curacao in San Jose three days later.
