[MLS] Mexican forward Luis Landin, one of the biggest Designated Player busts in MLS history, has been released by the Houston Dynamo almost a year after he arrived on loan, and the Dynamo has replaced him with Ghanaian midfielder Anthony Obodai, most recently of Dutch club RKC. In other news, popular assistant coach John Spencer had left the team.

Landin played only 796 minutes in parts of two seasons and scored two goals.

The Dynamo midfield needs help following the departure of U.S. World Cup players Stuart Holden and Ricardo Clark in the offseason and the season-ending injury to Geoff Cameron.

Obodai has been working out with the Dynamo in advance of the opening of the MLS transfer window on July 15.

Spencer, the former Scottish international, came to the Dynamo in 2006. He has often been mentioned as a head coaching candidate at other MLS clubs, most recently the expansion Portland Timbers, who will begin play in 2011.
