The other match in the pair for the Ticos is a Sept. 10 match at Jamaica.
Saborio has played in all 12 of Costa Rica's qualifying matches, scoring 7 goals in the process, for a joint fourth-place held with Jerry Bengston of Honduras and Clint Dempsey of the United States. He's also the only Costa Rican to have scored more than two goals in qualifying.
Barring injury, Saborio is unlikely to miss a match for Real Salt Lake, but a quick turnaround after the Jamaica match could render him difficult to select for RSL's match against Seattle on Sept. 13.
Costa Rica is currently in a strong position in qualifying, sitting with 11 points — behind the U.S.'s 13 — but with Meixco on 8 and Honduras on 7, it could get dicey down the stretch.
