The Cowboys have waived running back Trey Williams, according to Field Yates of ESPN.com (on Twitter). Williams is no longer needed on the roster with a certain superstar set to make his return this week.

Williams, a former standout at Texas A&M, was promoted from the practice squad to the active roster roughly three weeks ago. He dressed for two games and carried the ball twice for 12 yards.
He has now been displaced as Ezekiel Elliott is set to return from suspension. Elliott will resume his role as the Cowboys’ top running back with Alfred Morris and Rod Smith as his backups.
If Williams clears waivers, the Cowboys may look to re-sign Williams to the practice squad.
If the Giants were smart they would get Alfred orris in
The off season. But who said their smart
He won’t be able to do anything behind that line
