Andrew Driver out with Achilles injury on this week's injury report

Driver injured Achilles during Chicago match, will not be available vs. Columbus

One up, one down.

That's largely been the recipe for Houston Dynamo injuries this season. Last week, Brad Davis returned to full fitness after a hamstring strain but now midfielder Andrew Driver is listed as out with Achilles tendonitis in this week's injury report, presented by Houston Methodist.

Driver sustained his injury early in last Saturday's match against the Chicago Fire and was forced to exit in the 15th minute, clearing the way for Davis' return. Head coach Dominic Kinnear spoke to the media after training on Friday, and indicated that Driver's situation is "day-to-day" at the moment. Forward Calen Carr is also listed as out for the Columbus match, as he continues to work his way back from his ACL injury.

Brian Ching, Anthony Arena and Omar Cummings remain listed as questionable. Ching and Cummings are recovering from adductor strains, while Arena is listed with an ankle sprain.

For Columbus, Eddie Gaven and Glauber suffered ACL tears earlier this season. Forward Aaron Schoenfeld will also miss tonight's match with a shoulder sprain. Defender Eric Gehrig is questionable with a right ankle sprain.
