IRVING, Texas -- The death of Dallas Cowboys practice squad member Jerry Brown in a car accident is raising new questions about the effectiveness of the league's warnings and safety nets.
Brown died Saturday and teammate Josh Brent has been charged with manslaughter after police say he caused the wreck by speeding and driving drunk.
It has brought the NFL Players Association's safe ride program back into focus about three years after it was revamped over concerns that enough players weren't using it.
Union spokesman Carl Francis says the program is a strong point of emphasis, and every player's membership card includes the contact information.
Still, Jacksonville cornerback CB Rashean Mathis, the team's union representative, says players rarely, if ever, use the program.
