The Dallas Cowboys’ move to a focus on the tight ends was made complete Friday with the release of fullback Lawrence Vickers.The move saved the Cowboys $1.2 million, Vickers’ salary next season.It was also not surprising. Vickers had been on the roster bubble since the draft in April when the Cowboys drafted tight end Gavin Escobar in the second round and promised to move to a two-tight end attack with Pro Bowler Jason Witten. The Cowboys also have veteran tight ends James Hanna and Dante Rosario on the roster.Vickers appeared in 16 games for Dallas in 2012 with six starts. He finished the season with three rushes for 11 yards, 13 catches for 104 yards and two tackles on special teams. He originally signed with Dallas on March 14, 2012. The Cowboys have 89 players on the roster and could add a player before the start of training-camp practices July 21.
