[MLS] The Houston Dynamo got more bad news on Monday: young star Geoff Cameron, whom it was accounting upon to replace the departed Ricardo Clark in midfield, was lost for the season with knee injury suffered in Saturday's 2-0 loss at Chicago. It marked the fourth time in five games the Dynamo has lost a player with a first-half injury ...

Cameron, who earned Best XI honors as a defender in 2009, was diagnosed with a ruptured right PCL and will undergo surgery later this week.

Injuries have cost the Dynamo the services of players in all but one game this season:

March 27. Eddie Robinson, who played just one game in 2009 because of a knee injury, strains his left hamstring and leaves the season opener at FC Dallas in the 43rd minute. He misses the home opener five days later.

April 1. Forward Brian Ching is carried off the field in the 30th minute of the home opener against Real Salt Lake after straining his left hamstring. He's expected to miss 4-6 weeks, jeopardizing his chances of making the U.S. World Cup team.

April 10. The versatile Richard Mulrooney strains his knee knee and is forced to leave the Dynamo's rematch of the 2009 Western Conference final against Los Angeles in the 28th minute. He hasn't played since.

April 24. Again in the 28th minute, another knee injury. Cameron limps off the field and heads straight to the locker room at Chicago's Toyota Park. Canadian Adrian Serioux replaces Cameron and Jamaican Lovel Palmer moves into Cameron's slot in midfield, but the Dynamo struggles and falls to the Fire, 2-0.
