Hernandez asked Mexico manager Juan Carlos Osorio and his coaching staff for a "special permission" because of a personal issue. There was no suggestion from the FMF statement as to the motives behind Hernandez's absence.
The 29-year-old striker hasn't been active on social media since Saturday, although he did appear on Saturday at the official announcement of the Mexican players' association.
Lozano suffered a dislocated right elbow in training last Saturday and will return to PSV to begin treatment, according to a statement from the Mexican federation (FMF). The 22-year-old equalized for El Tri in its match last Friday against Trinidad and Tobago, while Hernandez netted Mexico's second in its 3-1 World Cup qualifying victory. The PSV winger signed for the Dutch club from Pachuca last summer and has scored six goals in his first six Eredivisie games
