IRVING, Texas — Dallas Cowboys defensive lineman Josh Brent is facing an intoxication manslaughter charge after a one-vehicle accident that killed linebacker Jerry Brown, a member of the team's practice squad.

Irving police spokesman John Argumaniz said the accident happened about 2:20 a.m. Saturday in the Dallas suburb. Argumaniz says Brent was speeding when the vehicle hit a curb and flipped at least once.

Argumaniz says Brown was found unresponsive at the scene and pronounced dead at a hospital.

The police spokesman says officers conducted a field sobriety test on Brent and arrested him. The charge was upgraded after Brown was pronounced dead.

The Cowboys didn't immediately respond to an email request for comment.
