The Dallas County District Attorney's office Wednesday announced the indictment against Brent, who police say was driving during a Dec. 8 crash that claimed the life of his passenger, Cowboys linebacker Jerry Brown.
Authorities said Brent, 24, had a blood alcohol content of .189 -- more than twice the legal limit -- when he hit a curb and flipped his car while traveling at an "unreasonable speed" on an Irving, Texas, street after leaving a Dallas nightclub.
While Brent suffered only minor injuries in the crash, Brown was pronounced dead after being taken from the scene to a local hospital.
The defensive lineman remains free on bond while awaiting the setting of a trial date.
Brent's bail was reduced from $500,000 to $100,000 last week after Dallas County District Attorney Craig Watkins said he wasn't a flight risk, The Dallas Morning News reported.
