The federation plans to restructure its referee department after the Gold Cup was mired by a series of controversial calls.
CONCACAF found "no clear or convincing evidence of match fixing" at the Gold Cup during a review of its referee department, the federation announced Wednesday.
Acting general secretary Ted Howard oversaw the probe, which came after several controversial calls went in Mexico's favor during El Tri's path to the Gold Cup title in July. The review helped CONCACAF identify "areas for administrative improvement" as the federation restructures its referee department and hires a new director of refereeing.
