Brent was released on a court order early Sunday, the Dallas Morning News reported.
He is currently charged with intoxication manslaughter for the Dec. 8 single-car crash that killed fellow Cowboy Jerry Brown.
Authorities said Brent had a blood-alcohol level of twice the legal limit for driving that night
Brent had been out on bond until he was sent back to jail June 27 for failing a June 19 drug test and his bond was declared insufficient.
George Milner, Brent's attorney, said he plans on requesting a gag order against District Attorney Craig Watkins, who said during a radio interview that Brent "needs to go to prison."
