The 27-year old midfielder arrives in Kansas City in exchange for allocation money with the Revs picking up SKC’s natural first round pick in the 2014 MLS SuperDraft and natural second round pick in the 2015 MLS SuperDraft.
Feilhaber, who has previously played with Hamburg, Derby County and Aarhus, was thrilled to be joining a club where he feels plenty of success can be achieved.
"I am really excited to come to Sporting Kansas City," Feilhaber said.
"It is a top-class organization and team in Major League Soccer. My goal is to help the team however I can. I cannot wait to play in the best stadium in the League and in front of a great fan base. I am already hyped for the first home game."
