When the Dallas Cowboys opened their off-season program Monday, one question was whether they would be joined by defensive tackle Josh Brent, who is facing intoxication manslaughter charges for the Dec. 8 death of practice-squad linebacker Jerry Brown.Those workouts began Monday and Brent was no where to be found. But that doesnt mean he wont be there eventually.Brent is scheduled to stand trial in Dallas County on Sept. 23 and faces up to 20 years in prison.He remains free on $100,000 bond and must wear an electronic monitoring ankle bracelet.Because he is not suspended by the Cowboys or the NFL, Brent could join the rest of his teammates for not only the voluntary off-season program, but the mandatory minicamp in June, as well as training camp in July.According to a team source, there has been no agreement between Brent and the Cowboys for him to stay away.Absent an agreement, players on a roster are generally permitted to attend and participate in off-season team activities, per a league source. Its unlikely Brent will play for the Cowboys next season. But the team or the league has yet to rule officially on his status, opening the door for him to presumably participate in team activities in the interim. His $630,000 salary still counts against the salary cap.NFL Commissioner Roger Goodell has the authority to take action prior to the resolution of the case in court but has yet to do so. Clarence E. Hill Jr.Briefly • Giants: Restricted free agent receiver Victor Cruz did not show up at the team facility Monday for the start of off-season workouts. Cruz has not signed his free-agent tender, hoping instead for a long-term contract. He isnt contractually obligated to show up until he signs one or the other. • Saints: Veteran quarterback Seneca Wallace signed a one-year contract and joins Drew Brees and Luke McCown as Saints quarterbacks. • Lions: Receiver Brian Robiskie, who was released last week, re-signed on a one-year contract. • NFL: Next seasons schedule, which was due to be released Tuesday, is not ready but could be in the next week or two, according to spokesman Greg Aiello. • Losing Faith: Singer Faith Hill, who has been singing the opening theme to Sunday Night Football for six seasons, said she will no longer do so, tweeting its time 2 let someone else rock the open.
