Terms of the deal were not disclosed, but fourth-round picks last season signed four-year deals worth around $2.5 million.

Drafted in the fourth round out of Michigan State, Cousins becomes the seventh of Washington’s nine draft picks to sign.

First-round pick Robert Griffin III and third-round pick Josh LeRibeus remain unsigned but continue to take part in offseason practices.

Cousins is competing with veteran Rex Grossman and Jonathan Crompton to be Griffin’s backup.
