The Portland Timbers believe that midfielder Diego Valeri sustained an anterior cruciate ligament (ACL) tear during Saturday's match against FC Dallas.

Valeri has undergone an MRI and will receive more testing today.

Valeri went down in the 26th minute of Saturday's game after appearing to be clipped by FC Dallas midfielder Andres Escobar.

After staying down on the field for a few minutes and being evaluated by trainers, Valeri somehow managed to continued to play until the end of the half.

Timbers coach Caleb Porter removed Valeri from the game at halftime.

Valeri finished the 2014 season as Portland's leader in goals (11) and assists (14). Valeri's 11 goals set an MLS club record for most goals in a single season and his 14 assists tied the Timbers all-time club record for most assists in a single season. Valeri's performance earned him a selection to the MLS All-Star team and put him in the conversation to win the MLS MVP award.

This will be the second consecutive offseason that Valeri spends recovering from injury. The midfielder underwent sports hernia surgery during the 2013 offseason.

We will continue to provide updates about Valeri's injury as information becomes available.
