In court documents filed Thursday morning, the Dallas County District Attorney's office is asking for a hearing to revoke Brent's bond, which could possibly land him in jail as he awaits trial for intoxication manslaughter.
Brent is accused of intoxication manslaughter in the December 2012 death of friend and teammate Jerry Brown.
Brent appeared in court May 24 when questions were raised about whether he'd consumed alcohol based on readings from an ankle monitor he wears as a condition of his bond.
At that time, Brent was ordered by the court to submit to a urinalysis test to insure his compliance with the bond agreement. The results of the test showed Brent tested positive for marijuana use within 30 days of the administering of that test.
Conditions for Brent's bond specify that he is not allowed to consume any alcohol, marijuana, narcotics, dangerous drugs or inhalants as long as his case is pending before court.
The Dallas County District Attorney's office would not comment on the positive drug test and lab results, but submitted the results of the test as part of their motion requesting a bond revocation hearing.
Brent's attorney, George Milner, when contacted by phone, said he is unaware of the motion and accuses the District Attorney's office of going after Brent maliciously because he's a Dallas Cowboy.
The documents indicate Milner was served with the motion Wednesday.
Brent is still on the Dallas Cowboys roster but is not actively participating in organized team activities.
No court date has been set yet to hear the motion which could subject Brent to even more stringent monitoring while out on bond, raise his bond fee or result in him going to jail while awaiting trial.
