Dallas Cowboys nose tackle Josh Brent was arrested Saturday morning for intoxicated manslaughter after an accident that killed his teammate Jerry Brown.

John Argumaniz, Irving's police spokesman, said the accident happened at around 2:20 am. Brent was allegedly speeding when the vehicle hit a curb and flipped, Argumaniz said.

The 25-year-old Brown was found unresponsive at the scene and pronounced dead later at a hospital. He was signed to the Cowboys' practice squad and was Brent's college teammate at Illinois.

"We are deeply saddened by the news of this accident and the passing of Jerry Brown," Cowboys owner Jerry Jones said in a statement. "At this time, our hearts and prayers and deepest sympathies are with the members of Jerry's family and all of those who knew him and loved him."

Brent was previously arrested and sentenced in 2009 to two years of probation and 60 days in jail as part of a plea agreement after a drunk-driving arrest in Illinois.

Brent was the Cowboys' starting nose tackle when Jay Ratliff was sidelined by an injury.
