The Houston Texans are promoting linebackers coach Mike Vrabel to defensive coordinator, a source told ESPN's Adam Schefter.
Romeo Crennel, the Texans' defensive coordinator for the past three seasons, will stay with the team as assistant head coach. His contract as defensive coordinator was set to expire next Tuesday.
The news of Vrabel's promotion was first reported by The MMQB.com.
Vrabel, 41, turned down an offer from then-San Francisco 49ers coach Chip Kelly to be his defensive coordinator last January.
He played linebacker in the NFL for 14 seasons and was selected for the Pro Bowl in 2007 when he was with the New England Patriots.
