Cowboys officially sign Ryan Williams

The Dallas Cowboys have announced that they’ve sign former Cardinals running back Ryan Williams.

The Cowboys are already churning the roster and it’s still mid-May.

But to add some depth and perhaps some competition to the running back position, the Cowboys added veteran Ryan Williams, officially signing the fourth-year pro on Monday. Williams, the 38thoverall pick of the Cardinals in 2011, has battled through injuries in his three years in Arizona. But after an impressive workout Saturday at Valley Ranch in between rookie minicamp practices, the Cowboys agreed to sign him.

In doing so, the Cowboys waived running back Glasco Martin, an undrafted rookie from Baylor. Martin’s status with the club was shaky all along considering he was the only player among the 24 undrafted rookies not to get a signing bonus.

Williams only appeared in five games with Arizona during the past two seasons, due to injuries.
