Clark, Dynamo suffer blow

Ricardo Clark is expected to be out 3-4 weeks after suffering sprained right knee ligaments in the 2-0 win over Pachuca.
The injury will force Clark to miss the upcoming return leg of the Concacaf Champions Cup semi-finals in Mexico.
Additionally Clark will miss upcoming friendlies against Ecuador and Guatemala after being called in by U.S. Manager Bob Bradley.
The Clark injury reminds us of the importance of depth this year for the Houston Dynamo involved in 3 tournaments and league play.
Last year it was Adrian Serioux who generally filled in for Clark in his abscence. Serioux’s qualities were tailor made for moving between a central defensive role and a holding midfield role. Serioux has since moved on to FC Dallas and is currently out 6 months with a knee injury. Clark’s ability to cover ground and decision making out of that position will be tough to replace. Other than Serioux few have played in that postion.
How do you cover for Clark in a huge international game on the road? If the Dynamo can get past Pachuca they will be guaranteed of either a FIFA World Club Championship berth or a Copa Sudamerican berth.
