Schellas Hyndman will end a five-year spell as head coach of FC Dallas on his own terms at the end of the season.
Hyndman announced on Friday he has decided to step down from his post at the Toyota Stadium in Frisco, having taken the helm in June 2008 following the dismissal of Steve Morrow. FC Dallas failed to reach the post-season play-offs this year but Hyndman led the team to the 2010 MLS Cup final, where they lost to the Colorado Rapids. He was also named coach of the year in 2010.
Hyndman, 61, said on the club's official website: "I truly appreciate the opportunity to be a part of the FC Dallas family for the last five years. After a lot of thought and consideration, I feel the time is right for me to step down as head coach of FC Dallas."
FC Dallas chairman Clark Hunt said: "My family and I have a tremendous amount of respect and admiration for Schellas both as a coach and as a person, and we sincerely appreciate his contributions to the club over the last five-and-a-half seasons.
"Having had the pleasure of knowing him for the last 30 years, I have seen first-hand his commitment to his craft and the passion he has for the game. We wish him well in the next chapter of his life, and he will be missed."
FC Dallas have just two games remaining in their season, the first of which takes place at home against Seattle Sounders on Saturday. Hyndman will sign off with the trip to face San Jose Earthquakes on 26 October.
