Portland Timbers midfielder Diego Chara broke a bone in his foot while teammates Darlington Nagbe and Larrys Mabiala also left Monday's playoff game with injuries.

The Timbers managed a goalless draw in their first leg at the Houston Dynamo -- thanks in part to a controversial video review -- but they are facing an injury crisis ahead of the return leg on Sunday.

Chara went down on a non-contact play at the end of the first half and was taken off the pitch on a stretcher. He was on crutches after the game with his foot in a boot, and Timbers coach Caleb Porter said he had broken the fifth metatarsal bone in his right foot.
