To make room for Williams on the 90-man roster, the Cowboys cut undrafted rookie running back Glasco Martin, who played at Baylor.
Williams was the second-round pick by the Arizona Cardinals in 2011 but played in only five games in three seasons because of injuries. He missed his rookie season after rupturing the patella tendon in his right knee. He ran for 164 yards on 58 carries in 2012 before suffering a shoulder injury. He did not play in a game last season.
"He was a guy that we regarded very highly coming out in the draft,” Garrett said. “He was one of the best backs in the draft that year, and somebody we thought a lot of. He’s gone there, and he’s had some injuries, had injuries in ’11 and ’12. Then, he was injury-free last year but just didn’t play because of what their running-back situation was and their roster makeup. But he’s someone when we watched him on tape - he played mostly in 2012, before he hurt his shoulder - he looks like the back we saw coming out of school. We did our due diligence, and we feel like bringing in a guy like that in to compete at that running back spot is good for our team.”
The Cowboys have kept four tailbacks on the 53-man roster in recent years and Williams joins DeMarco Murray, Lance Dunbar and Joseph Randle as the veteran backs. The club also signed undrafted free agents Ben Malena and Glasco Martin, who took part in the weekend’s rookie minicamp.
“I’ve worked my tail off to get to this point,” Williams said. “It was a rocky road, but I got it done. Regardless of how anybody sees my career going, it was beneficial for me not to play last year and the other year I got hurt with my shoulder. It just gives my knee more time. This isn’t an easy injury to come back from at all. It worked for me.”
