Jack Del Rio is resigning from his role as a senior adviser for the Wisconsin football program. The former NFL coach was arrested early Friday on charges of operating a vehicle while intoxicated after a crash in Madison, Wisconsin.

Prior to Fickell announcing Del Rio’s resignation, school administrators released a statement saying they were aware of the incident and take such matters very seriously.

Del Rio, 61, was arrested at approximately 12:35 a.m. on Friday after driving his vehicle into a street sign, also breaking a fence and stopping in a yard, according to Madison Police. Witnesses pointed officers arriving on the scene to Del Rio, who had left the vehicle and was walking away from the crash.

Officers said Del Rio “showed signs of impairment” and admitted to driving the crashed vehicle in the incident report. No injuries were reported from the scene. He was arrested on the scene for first-time OWI and eventually released.

Del Rio was hired by Fickell in late August to work with the Badgers’ offense and defense, in addition to helping with personnel and serving as a sounding board for the head coach. It was Del Rio’s first job in college football after nearly 40 years in the NFL as a player and coach.

Last season, Del Rio was fired as the Washington Commanders‘ defensive coordinator after Week 12. At the time he was dismissed, the Commanders’ defense was ranked No. 32 in the NFL.

He coached for seven NFL teams, including stints with the Carolina Panthers, Denver Broncos and Commanders as a defensive coordinator, and as a head coach for the Jacksonville Jaguars and then-Oakland Raiders. Prior to his coaching career, Del Rio played 11 seasons in the NFL as a linebacker, notably with the Dallas Cowboys and Minnesota Vikings, after being drafted in the third round in 1985 out of USC.

Wisconsin is 5-4 overall and tied for fourth in the Big Ten at 3-3. After a bye last week, the Badgers host No. 1 Oregon in Madison on Saturday.
