According to Irving police, Brent's car was traveling at a high rate of speed on a State Highway 114 service road before he hit the outside curb. The car flipped at least one time before coming to a rest in the middle of the service road.
When police arrived Brent was responsive and spoke to police officers. Brown was unresponsive and taken to a hospital where he was pronounced dead.
Brent, a three-year veteran, was booked in the Irving city jail at 4:14 a.m. Saturday morning.
Brown was signed to the Cowboys' practice squad earlier this season. He was also 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."
The Cowboys are flying to Cincinnati for Sunday's game against the Bengals and had no comment on the accident, other than to say Brent did not make the team's charter. The players were told on the plane just before takeoff of what happened after non-team personnel were asked to go outside.
