(Reuters) - Dallas Cowboys defensive lineman Joshua Price-Brent was arrested and charged with manslaughter on Saturday after practice squad teammate Jerry Brown Jr. was killed in the crash of a car driven by Price-Brent, police said.

Police in the Dallas suburb of Irving said that Price-Brent, 24, was driving at a high speed on a state highway at 2:21 a.m. when the car slammed into an "outside curb, causing the vehicle to flip at least one time before coming to rest in the middle of the service road."

Brown, 25, who was in the passenger seat, was pronounced dead at a nearby hospital a short time later. He was a linebacker on the professional team's practice squad.

Price-Brent failed a sobriety test and was booked into Irving jail charged with manslaughter for driving while intoxicated. He had emerged as a starter for the NFL team this year after Jay Ratliff, the team's starting defensive tackle, suffered injuries.

The arrest of Price-Brent came exactly a week after Kansas City Chiefs starting linebacker Jovan Belcher shot his girlfriend to death, then drove to the team training facility and killed himself.
