Davis, 34, won 2006 and 2007 MLS Cup championships with Houston for which he spent 10 seasons. His 123 assists and 392 games played rank third
and fourth on the all-time MLS regular season charts, respectively.
“I can’t believe that the last 15 years have gone by so fast and that this journey has come to an end,” Davis said in a statement. “Along the way, I have met a lot of great people and have had the privilege to play alongside many great players. There are so many individuals that I look forward to thanking who have made me the person and the player I have become.”
Davis spent two seasons at his hometown Saint Louis University before being taken third overall in the 2002 MLS SuperDraft by the MetroStars. After one season, he moved to the Dallas Burn, where he was a regular starter from 2003-2004. He then joined the San Jose Earthquakes in 2005, landing his first MLS All-Star selection and a Supporters’ Shield title during his only season in San Jose before the club relocated to Houston in 2006.
“Brad was one of the most naturally gifted soccer players I have ever been around,” said San Jose Earthquakes head coach Dominic Kinnear, who coached Davis in San Jose and Houston from 2005-2014. “He has had a great career and I wish him the best of luck. It was a pleasure to coach him for as many years as I did, and I felt lucky to have him on the field helping our team.”
Davis has two goals and one assist -- the lowest production of his career -- in 24 games for Sporting Kansas City, which he joined in 2016. He played for the USA at the 2001 Under-20 World Cup and 2014 World Cup.
“This was a very difficult decision for him," Sporting Kansas City coach Peter Vermes said. "Brad has been a tremendous professional throughout his career and during his time with us."
Sporting Kansas City made the 2016 MLS playoffs, where it faces Seattle in the Knockout Round on Thursday.
