When the Dallas Cowboys released fullback Lawrence Vickers, it saved $1.2 million against the salary cap and gave the team approximately $10 million in cap space. The Cowboys have three available spots on the 90-man training camp roster, so adding a fullback before Sunday's first training camp practice is a possibility. Cowboys owner/general manager Jerry Jones said the team most likely will sign a quarterback to fill one of the spots. But getting rid of Vickers means the Cowboys could devote four roster spots to tight ends and four more to running backs for the 53-man roster.
