Costa Rica look set to start Joel Campbell up top after dropping Jairo Arrieta. Alvaro Saborio is recovering from an injury and is on the bench. They've made a number of changes and their formation is anyone's guess, but it looks like they're packing the center of midfield.
Mexico lineup (4-4-2): Jose Corona; Carlos Salcido, Hector Moreno, 'Maza' Francisco Rodriguez, Gerardo Flores; Andres Guardado, Hector Herrera, Jesus Zavala, Pablo Barrera; Aldo de Nigris, 'Chicharito' Javier Hernandez
Costa Rica lineup (4-3-3): Keylor Navas; Jhonny Acosta, Giancarlo Gonzalez, Michael Umaña, Cristian Gamboa; Michael Barrantes, Junior Diaz, Yeltsin Tejada, Joel Campbell, Bryan Ruiz, Cristian Bolaños
Kickoff is at 8:10 p.m. ET, delayed 10 minutes due to Costa Rica arriving late at the Azteca. You can catch the game on ESPN or Univision Deportes in the United States.
