Having won the first leg of the Western Conference semi-final 1-0 at LA Galaxy on Sunday, Galaxy hit back in some style to win the second leg 3-1 at San Jose on Wednesday night to take the tie 3-2 on aggregate.
Simon played the full 90 minutes and had three efforts at goal but a double from his former team-mate and Spurs legend Robbie Keane saw the Galaxy home.
It means Earthquakes - who finished top of the Western Conference in the regular season - have to settle for the prestigious Supporters Shield award to mark a season where they finished with the best regular season record in the MLS.
However, they will miss out on being crowned MLS champions for another year as Galaxy continue to defend their title.
Galaxy will now play either Real Salt Lake or Seattle Sounders in the Western Conference Final before facing the winners of the Eastern Conference in the MLS Cup Final on December 1.
Jordan Archer was inspired as Wycombe earned an important point at Aldershot on Tuesday night.
The young goalkeeper made an incredible triple save to deny the Shots in the first half as it ended 0-0 at the Recreation Ground.

Jordan kept Wycombe on level terms in the opening half-hour but the game changed after that as Shots' Anthony Tonkin was sent off. Wycombe had the better of it from there but it remained goalless. Jack Munns was an unsued substitute for Aldershot.
