The Dallas Cowboys plan to move defensive tackle Josh Brent to the reserved non-football injury list, ESPN reports.

That would clear a roster spot for the Cowboys and allow him access to the team’s training facility, where he could have contact with teammates and coaches.

Brent, who is out on $500,000 bond after being charged with intoxicated manslaughter in the death of teammate Jerry Brown on Saturday, is emotionally unable to play, a source told ESPN. Brent attended a memorial service for Brown, a friend of his since college, Wednesday. Brown’s mother, Stacey Jackson, had asked Brent to sit with the family during the service, Cowboys owner Jerry Jones said.

“She’s an amazing lady,” Cowboys executive vice-president Stephen Jones said of Jackson. “They’re an amazing family in general, the stepfather, the father. Amazing, amazing family. Obviously a lot of strength in terms of what they’re about.”

Brown was pronounced dead at a Dallas hospital after the car Brent was driving went out of control and flipped several times. According to the county coroner, Brown died from blunt force trauma to the head and neck. Brent suffered neck and wrist injuries. Witnesses who arrived on the scene shortly after the crash differ over whether Brent was spontaneously trying to pull Brown from the car, which was catching fire, or whether he was urged to try to help Brown.

In the wake of the accident, the Cowboys reportedly are discussing installing electronic devices in players’ cars that would immobilize them if a driver is impaired. That would most likely require input from the NFL Players Association, but Cowboys consultant Calvin Hill told the Dallas Morning News the idea was under consideration.
