The Dallas Cowboys have released Tristan Vizcaino.

Brandon Aubrey is the only kicker on the 90-man roster after the release of Vizcaino.

Robbie Gould and Mason Crosby remain available, but the Cowboys have yet to express interest in adding a veteran.

The Tennessee Titans released offensive lineman Jamarco Jones after his second altercation in practice this week.

Thursday's altercation happened after his crackback block on linebacker Chance Campbell. Fellow linebacker Azeez Al-Shaair got in Jones' face and the two had to be separated.

Mike Vrabel said the block would have been a penalty in a game.

"We don't want to practice like that," Vrabel said. "We talk all the time about being competitive and going to that line, and certainly not going to do anything that hurts the team. We don't want to see that."

Jones had gotten into a pushing match with Jeffery Simmons after one of the first plays during team period on Tuesday.
