Craven's agent Fadde Mikhail released a statement on Tuesday saying the safety has received medical clearance to resume football activities.
Cravens had been dealing with previously undisclosed health issues. Tuesday's statement makes it clear the 22-year-old was combating concussion problems.
Cravens was reportedly contemplating retirement when he left the Redskins before the season. The 53rd overall pick out of USC in 2016, however, plans to resume his career in Washington. He should rejoin a defense that could use a playmaker on the backend.
As a rookie, Cravens recorded 34 tackles, a sack, an interception, and five passes defended in 11 games.
