KANSAS CITY, Kansas -- Sporting Kansas City announced on Monday that the club has agreed to transfer forward Kei Kamara to Middlesbrough FC of the Football League Championship in England.

"Over the last four-plus years Kei's progression as a player has been tremendous," said Sporting KC Manager Peter Vermes.  "We appreciate his service to the team and to the club and we wish nothing but the best for him and his next challenge as a player."

In eight Major League Soccer seasons with four different teams, Kamara recorded 53 goals and 24 assists in 200 appearances (including playoffs).

Sporting currently tops Group 2 in the CONCACAF Champions League with a perfect 2-0-0 records thanks to away wins over Real Esteli and Olimpia.  The 29-year-old forward, a Sierra Leone international, did not appear in either game.

Kamara does have three goals in the confederation competition -- all with the Houston Dynamo -- including a brace at Pumas on September 30, 2008.

Sporting returns to Champions League play on September 17, when it welcomes Esteli to Sporting Park.
