Ryan Williams

As the Dallas Cowboys prepare to depart for training camp in Oxnard, California, running back Ryan Williams has been released.

He was fourth in the running back chase to replace DeMarco Murray behind Joseph Randle, Darren McFadden and Lance Dunbar. Williams had two arthroscopic surgeries on his knee in the offseason, the most recent coming after the Cowboys' June minicamp.

Williams spent last year on the Cowboys' practice squad, spurning chances late in the season to join other teams' active rosters. The Cowboys rewarded him with a two-year deal that included a $240,000 signing bonus.
