Former Dallas Cowboys defensive tackle Josh Brent was released from jail on Sunday, according to the Dallas County sheriff's office.

Brent, 26, was convicted of intoxication manslaughter in January.

In December 2012, Brent drunken car crash killed his friend and teammate, Jerry Brown. He was sentenced to 180 days in jail and 10 years' probation.

It is not clear if Brent will have to report to a treatment facility to complete his sentence, which was expected to end in July.

Brent crashed his Mercedes sedan on a suburban Dallas highway after leaving a nightclub with Brown as a passenger. Brent had a blood-alcohol content level of 0.18 percent, more than two times the legal limit in Texas.

---Former NFL running back Rodney Thomas died on Saturday. He was 41.

Thomas died in his hometown of Groveton, Texas, at about 7 p.m. Saturday, according to Trinity County Justice of the Peace Rod Blair. The cause of death will not be determined until an autopsy is completed.

Thomas was a third-round draft choice of the Houston Oilers in 1995 out of Texas A&M. He rushed for 947 yards with five touchdowns his rookie season.

Thomas stayed with the franchise when it moved to Tennessee and became the Titans. He played in Super Bowl XXXIV against the St. Louis Rams. He retired in 2001 after spending one season with the Atlanta Falcons. For his NFL career, Thomas ran for 1,973 yards.

---Minnesota Vikings quarterback Christian Ponder said he understands that he may be No. 3 on the depth chart when the season starts.

Veteran Matt Cassel is No. 1 on the depth chart and rookie Teddy Bridgewater is also getting more reps in practice than Ponder, the incumbent starter.

Ponder was a first-round draft choice in 2011.

"We'll see how it plays out once it goes to training camp," Ponder said, according to the St. Paul Pioneer Press, "but obviously there's an agenda to try to get Teddy ready, and Cassel's the starter right now."

---Vince Young apparently has come to grips that his NFL career is over.

The former Tennessee Titans starting quarterback told an Austin, Texas, radio station on Saturday that, though he has not filed papers with the league, he considers himself retired as an NFL player unless a ironclad offer comes from out of the blue.

"It's definitely official I think in my book," Young told KXAN. "Unless we get a great opportunity, something guaranteed ... other than that I've started moving forward in some things.

"I love the NFL, will love the game always, but I'm kind of moving forward and moving on right now."

Young was named to two Pro Bowls while compiling a 30-17 record as the Titans' starting quarterback. He believes a spat with then-Tennessee coach Jeff Fisher damaged his reputation.

"I had my ups and downs," Young said. "I made the mistake of getting in to it with my coach and that kind of hurt me a whole lot. When you go to different teams, they already have a bad perception of you. When that's out there, there's nothing you can do."

Young spent the 2011 season with the Philadelphia Eagles as a backup to Michael Vick and since then has struggled to find work.

He has been in camp with the Buffalo Bills, Green Bay Packers and, most recently, the Cleveland Browns. But none of those worked out.

Young said in April that he is planning to work for the University of Texas, where he played college football, if an NFL job is not there for him.
