The move Wednesday came a day after a memorial service for practice squad player Jerry Brown, Brent's close friend who was killed in a car accident when police say Brent was driving drunk. Brent is facing charges related to the accident Saturday morning.
Cowboys executive vice president Stephen Jones says the team wants to be able to stay in contact with Brent, and for the player to stay in contact with teammates. Jones says those things are important.
Dallas signed defensive tackle Brian Schaefering, who was released by Cleveland before this season.
