DALLAS (CBSDFW.COM) — Former Dallas Cowboys DT Josh Brent, who was previously convicted in a drunken driving crash that killed a teammate, is now wanted for violating his probation.

The Dallas County Sheriff’s office says a warrant was issued for the arrest of Josh Brent after the former defensive lineman was charged with assaulting a police officer Sunday.

Brent was arrested June 30 in Coppell after police said the 31-year-old resisted an officer trying to handcuff him for public intoxication.

In 2014, Brent was convicted of intoxication manslaughter for his role in the crash that killed teammate Jerry Brown Jr. Brent was sentenced to 180 days in jail and 10 years’ probation.

It was not immediately clear if Brent was in custody, or if he had an attorney.
