Former National Football League quarterback Tony Romo was arrested on suspicion of operating a vehicle while intoxicated in Milwaukee, Wisconsin, on Thursday evening, according to the Milwaukee County Sheriff’s Office.

The 46-year-old, who now works as CBS Sports’ lead NFL game analyst, was stopped by deputies while driving southbound on Interstate 43 shortly after 18:00 local time. An arrest report stated he performed poorly on field sobriety tests and was taken into custody, booked at the county jail, and released later that night. A first court appearance is set for 21 September. The incident occurred while Romo was in his home state to compete in the Wisconsin State Amateur golf tournament; he finished tied for 74th place on Thursday.

Authorities have not disclosed the reason for the initial traffic stop, nor released any blood alcohol concentration or toxicology results. No aggravating factors, such as the presence of a minor in the vehicle, have been alleged. Local media, citing sheriff’s department records, note that this is Romo’s first arrest for an impaired-driving offence.

Romo, a native of Burlington, Wisconsin, played 14 seasons for the Dallas Cowboys, retiring in 2017 as the franchise’s all-time leader in touchdown passes. Since then, he has been a fixture on CBS’s top NFL broadcasts, earning praise for his play-predicting analysis. Under Wisconsin state law, a first operating-while-intoxicated violation is typically treated as a civil offence, carrying a forfeiture of $150 to $300, a mandatory surcharge, and possible licence revocation of six to nine months.

The sheriff’s office has said the matter remains under investigation. CBS declined to comment on the arrest.
