Manchester United boss Sir Alex Ferguson has ordered rest for Javier Hernandez.
The Daily Star says Hernandez has just helped Mexico win the Gold Cup but Fergie is worried about burn-out and has given him three weeks off.
Hernandez, who scored 20 goals for United in his first season, will not join the squad until the second week of their trip to America.
Hernandez is not expected to play in any of the pre-season games on tour.
He will make his return to action in Paul Scholes' testimonial against New York Cosmos in August or the Community Shield clash with rivals Manchester City.
