Dallas Cowboys practice-squad linebacker Jerry Brown was killed in a one-car accident Saturday and teammate Josh Brent was charged with intoxication manslaughter.

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

Argumaniz says the 25-year-old Brown was found unresponsive at the scene and pronounced dead at a hospital.
