IRVING, Texas (AP) - The Dallas Cowboys have waived running back Ryan Williams and receivers LaRon Byrd and Jamar Newsome while acquiring defensive end Lavar Edwards in a trade with Tennessee.
Two of the team's five seventh-round draft picks this year were waived Saturday, cornerback Terrance Mitchell and linebacker Will Smith.
Williams, a 2011 second-round pick who had three injury-filled seasons with Arizona, was Dallas' leading rusher in the preseason but missed the finale with a groin strain.
Byrd and Newsome were the top two receivers in the exhibition games, but the Cowboys went to training camp all but set at the position.
Edwards, taken in the fifth round by the Titans in 2013, was acquired for a seventh-round pick next year. He played in seven games.
