Mexico coach Aguirre left bloodied after object thrown from crowd
Aguirre was walking along the touchline to shake hands with counterpart Reinaldo Rueda after the match when he was hit on the top of his head by the can, with blood seeping from the wound.
"This is football, and there's no point in mentioning the other stuff because I'm not one to complain," Aguirre told reporters after the match at the General Francisco Morazan Stadium in San Pedro Sula, Honduras.
CONCACAF said it strongly condemned the incident.
"The security of the teams and fans is a priority for Concacaf. These types of violent behaviors have no place in football," the governing body added in a statement.
"The incident will now be referred to the Concacaf Disciplinary Committee for further review and investigation."
Aguirre took charge of Mexico's national football team for a third time in July, replacing Jaime Lozano who was sacked after a disappointing Copa America group-stage exit.
