The Houston Texans will move Romeo Crennel back to the role of defensive coordinator following the departure of Mike Vrabel to the Tennessee Titans, a source told Ian Rapoport of NFL Network.
Crennel was the Texans' DC from 2014-16. He was moved to assistant head coach to accommodate the promotion of Vrabel last offseason.
The Texans finished first in total defense under the 70-year-old's guidance in 2016. Crennel also helped star defensive end J.J. Watt earn back-to-back Defensive Player of the Year awards in 2014 and 2015.
