Lletget is out for most of the
summer, while Jones should remain out for a couple of more weeks.
Husidic's injury left first-year Portuguese Joao Pedro as the only established central midfielder but Pedro himself had to leave the game in the 87th minute with what was suspected to be a hamstring issue.
Rafael Garcia, who replaced Husidic on Sunday, has started just 10 games in his six seasons with the Galaxy. Jaime Villarreal, who replaced Pedro, was making his MLS debut.
Ten days earlier, the Galaxy placed defender Robbie Rogers on their season-ending injury list due to complications from his offseason surgery to repair nerve damage in his left ankle.
