Houston Texans assistant head coach Romeo Crennel is expected to take over as the team’s defensive coordinator, according to a source.

Footballguys View: With Mike Vrabel moving on to be the head coach of the Titans, the Texans need to find someone to run their defense. Crennel held the position with the Texans until he was promoted to assistant head coach last year. The Texans are coaching the Senior Bowl next week, so moving Crennel over makes sense.
