In addition, Chivas have signed Ryan Finley from Columbus Crew in exchange for another draft pick.
"We are very happy to add Marvin Chavez and Ryan Finley to our club as they will immediately bolster our attack," said Chivas USA head coach Wilmer Cabrera.
"Chavez is one of the best wide midfielders in the League and is very versatile at creating scoring opportunities. Finley will fit perfectly in our plan as a center forward, as his mobility and approach to the game will support and complement Erick Torres' skills up top."
