The U.S. national team isn't alone in sorting through last-minute injury issues ahead of Wednesday's all-important FIFA international fixture date.
U.S. rival Mexico has had Giovani dos Santos withdraw from El Tri's roster ahead of Wednesday's clash with Nigeria in Atlanta with a left calf injury. Bicycle-kicking hexagonal hero Raul Jimenez has been called in to replace him, the Mexican federation announced Monday.
Dos Santos was injured in Villarreal's 1-1 draw with Real Betis on Sunday, a game in which he played all 90 minutes. He is the second Mexican player to withdraw from the friendly after Miguel Layun suffered a shoulder injury.
Dos Santos was one of eight European-based players originally called in by Miguel Herrera for the match, which will take place at the Georgia Dome. Others include Manchester United forward Javier Hernandez, Bayer Leverkusen's Andres Guardado and FC Porto duo Hector Herrera and Diego Reyes.
Dos Santos is a lock to make Mexico's World Cup roster, but he won't have another opportunity to train with the Mexican team ahead of the final roster cut, given that Wednesday is the final official FIFA date before the final batch of friendlies in the build-up to Brazil.
Here is Mexico's roster for Wednesday in full after the personnel change:
GOALKEEPERS: Jesús Corona (Cruz Azul), Moisés Muñoz (América), Guillermo Ochoa (AC Ajaccio)
DEFENDERS: Héctor Moreno (Espanyol), Rafael Márquez (León), Francisco Javier Rodríguez (América), Juan Carlos Valenzuela (América), Diego Reyes (FC Porto), Paul Aguilar (América), Enrique Pérez (Atlas), Miguel Ponce (Toluca)
MIDFIELDERS: José Juan Vázquez (León), Juan Carlos Medina (América), Andrés Guardado (Bayer Leverkusen), Héctor Herrera (FC Porto), Luis Montes (León), Carlos Peña (León), Javier Aquino (Villarreal), Isaac Brizuela (Toluca) FORWARDS: Raúl Jiménez (América), Alan Pulido (Tigres), Oribe Peralta (Santos Laguna), Javier Hernández (Manchester United)
