Brent is charged with intoxication manslaughter and faces up to 20 years in prison if convicted, though he could also get probation. Suburban Dallas police accused Brent of driving with a blood-alcohol content more than twice the legal limit the night of the crash.
He has also tested positive twice for marijuana while out on bond, and was briefly jailed after the second test. He is again out on bond, but under stricter conditions that include monitoring for drugs and alcohol, and is banned from driving.
Owner Jerry Jones and coach Jason Garrett both said they supported Brent's decision to focus on life outside of football instead of the game. Jones told reporters that Brent's recent failed drug tests didn't affect his support of the player.
"I promised Jerry's mother that we would support Josh in every way we could," Jones said. "That's been our only thought since the accident is to support him and support our team in their support of him."

Assistant District Attorney Karyn Sinunu-Towery said Thursday that Brooks will not face prosecution after further investigation into allegations that Brooks repeatedly hit a teammate on the head with a beer bottle in a June incident.
According to police, Brooks hit teammate Lamar Divens with the bottle three times and then punched him in the face during an early morning argument on June 8.
