Just three years after the Arizona Cardinals drafted Ryan Williams with the 38th pick in the 2011 NFL draft, the running back was without a job, released last week after injuries limited him to just five games in three years with the Cardinals.

Williams landed on his feet, officially signing a contract with the Dallas Cowboys on Monday.

That deal was officially announced after Williams impressed Dallas coaches during his weekend workout, leading to reports that a deal was in the works. Undrafted rookie Glasco Martin was released in a corresponding move to open a roster spot.

Williams is not expected to challenge starting running back DeMarco Murray or even backup Lance Dunbar but could very well win the No. 3 job ahead of Joseph Randle.

Regardless, despite his solid workout, Williams will have to prove he's healthy if he's to earn a spot on Dallas' 53-man roster, as knee problems have plagued the 24-year-old's short NFL career.

The former second round pick was a "healthy" scratch in all 16 games for the Cardinals last season, despite the team employing a running back carousel.
