The Cowboys will fly to Oxnard, Calif., on July 19 and hold their first practice July 21.
The defensive tackle is currently eligible to take part in practice even though he did not take part in the offseason conditioning program, organized team activities and minicamp in the spring. The team has prepared as if Brent would not play in 2013 but has been waiting for the league office to make a ruling.
Brent is charged with intoxication manslaughter after a December car accident killed practice-squad linebacker Jerry Brown. Brent was released from jail Sunday after spending 11 days in jail for violating the terms of his pretrial release by allegedly testing positive for marijuana twice. The spokesman said Brent's case regarding the failed drug tests is under review.
As part of his release Sunday, Brent must wear a drug patch and not drive while continuing the previous alcohol monitoring. In March, a monitoring device alerted officials to the presence of alcohol in his system, in addition to the two failed drug tests.
NFL commissioner Roger Goodell can suspend Brent under the league's personal conduct policy before the legal system process is complete.
