Seattle ride a six-game unbeaten streak in the league into this match, and won in the U.S. Open Cup midweek.
The Galaxy will debut a new third jersey for Monday's game.
Los Angeles are unbeaten in 10 league matches, winning five and drawing five. Additionally, the Galaxy haven't lost at home this year.
Brian Perk should collect his first career MLS start. Donovan Ricketts picked up an injury and Josh Saunders was sent off in a 0-0 draw with the San Jose Earthquakes last week. Without both goalkeepers, Mike Magee played in goal for over a half to preserve the clean sheet.
Four of the Sounders' next five matches are on the road. However, Seattle are 3-2-4 away this year, including going unbeaten in the last four.
Landon Donovan will return to the Galaxy line-up after missing a month away with the U.S. national team at the Gold Cup. He is tied for the league lead in goals with eight.
David Beckham will miss the match with a stress fracture in the spine.
