We already knew Peter Nowak would not be pacing the sidelines for Saturday's match against San Jose.
But the Union boss will also miss his club's next match against Seattle on May 5 as well.
Major League Soccer commissioner Don Garber fined both Nowak and the Union $5,000 apiece along with the extra match for Nowak for a fracas that erupted after a studs-up challenge by Union defender Gabriel Farfan on Chivas USA defender James Riley.
Attempts to reach Nowak for comment were unsuccessful, but because the suspensions and fines were levied by the commissioner and not MLS' disciplinary committee, Nowak will not be appeal the ruling.
Chivas USA was not exempt from punishment as Garber also fined head coach Robin Fraser $500 for leaving the coaches box in and fined the club $2,500 for the behavior of its players and team staff.
Nowak will not be permitted to enter the stadium tunnel area, team locker room or field level until after conclusion of the game and can't communicate with players or coaches.
Nowak already had to serve a mandatory one-game suspension for being ejected from Saturday's match. Assistant coach John Hackworth and goalkeeper coach Rob Vartughian will take over on Saturday.
