Colorado Rapids midfielders Jacob Peterson and Jamie Smith have been ruled out for the remainder of the 2009 season. Peterson has been diagnosed with a torn anterior cruciate ligament (ACL) in his right knee after injuring himself in Wednesday night's match against San Jose. Surgery to repair the injury is scheduled to take place early next week.

Smith suffered a left knee injury on August 30 in the first half against the Houston Dynamo. He completed posterior lateral stabilization surgery and is currently going through rehabilitation with the Rapids' training staff. Smith's progress is on schedule, but the determination was made at this time that his return to the pitch this season would not be possible.
