A person in CONCACAF with knowledge of the requests says Panama and Costa Rica have formally asked for reviews of its referee procedures after both countries had questionable calls go against them late in Gold Cup knockout round games against regional power Mexico.

The person spoke on condition of anonymity Friday because he was not authorized to speak on the matter. CONCACAF had announced that the issue had been added for discussion to the agenda of Saturday's executive committee meeting but did not detail the requests.

In the final minute of extra time in Sunday's quarterfinal, Mexico was awarded a penalty kick with the game tied 0-0 and converted to beat Costa Rica. Then in Wednesday's semifinals, Panama led 1-0 when it was called for a hand ball in the box. Mexico again converted in stoppage time, then went on to win in extra time.
