Evans adds depth to 49ers' defensive line

Posted by ESPN.com's Mike Sando

The 49ers became one of four teams to add at least three unrestricted free agents from other teams when they reached agreement with defensive lineman Demetric Evans.

Evans comes to the 49ers from the Redskins. He projects as a backup defensive end. He is listed at 6-foot-4 and 287 pounds.

Aubrayo Franklin is the only true nose tackle on the team. Sopoaga played the position two years ago.

Evans becomes the third UFA to sign with the 49ers from another team. Fullback Moran Norris and receiver Brandon Jones were the others.
