(DALLAS) -- Josh Price-Brent, a 24-year-old defensive lineman for the Dallas Cowboys, is charged with intoxication manslaughter after a single-vehicle accident that killed 25-year-old line backer Jerry Brown Jr., according to the Irving Police Department.

Irving police spokesman John Argumaniz said the accident occurred around 2:21 a.m. on Saturday in the Dallas suburb, and Price-Brent was speeding when the vehicle hit a curb and flipped over.

Officers arrived on the scene and identified Price-Brent as the driver. The passenger, Brown Jr., was transported to a local hospital and was later pronounced deceased.

Police believe Price-Brent may have been intoxicated after giving him a sobriety test and are testing Price-Brent's blood samples for confirmation.

Price-Brent is being held at Irving City Jail.
