Josh Brent, the Dallas Cowboys defensive lineman who is awaiting trial on a charge of intoxication manslaughter, retired from the NFL today.

“This is the right decision for me, and something that I have given a lot of thought to,” Brent said in a statement released by the team.

“I am at a point where my main focus is all about getting the priorities in my life in order. Those priorities are more important than football. Doing the right things in life are more important than football. I love the game very much. I love my teammates, but this is the right thing for me to do.”

Brent was indicted after the car he was driving crashed and killed Jerry Brown, a Cowboys teammate who was his friend, on Dec. 8.  He is free on bond and has, until now, remained on the Cowboys roster despite not playing for them after the crash. Having structure did not keep him out of trouble, though. He was incarcerated last month for failing several drug tests and was released from jail July 7. His driver’s license was taken away and he is wearing a patch to detect drug use.

The Cowboys report for training camp this weekend and a ruling on a possible suspension for Brent, 25, had been expected soon.

“He’s basically wanting to concentrate on what he should be concentrating on in his life,” Cowboys owner and general manager Jerry Jones said (via the Dallas Morning News). “This allows him, in my mind, to do that.”
