The reason isn't yet known, but A right adductor strain has Juninho unavailable for the LA Galaxy in the match against Chivas USA. Pablo Mastroeni starts in his place. I'll update with the reason as soon as I get it. Hector Jimenez also steps back onto the bench with Michael Stephens starting in his place. Leonardo suffered a knock, so Kofi Opare starts in his place.
Otherwise, this is the same lineup that took the pitch in Portland.
LA Galaxy bench: Rowe; Meyer, Cochrane; Garcia; Jimenez, Courtois; Villarreal
