The Bucs are signing running back Kerwynn Williams, according to Ian Rapoport of NFL.com (on Twitter). Williams, who was released by the Lions last week, offers familiarity with head coach Bruce Arians and offensive coordinator Byron Leftwich from their time together with the Cardinals. 
In Arizona, Williams saw a decent amount of work as a reserve and even started in a handful of games in 2017, his final season with the team. All in all, he averaged 4.5 yards per carry, though the ’17 season was the only campaign in which he cracked 100 attempts on the year.
In other Bucs news, defensive end Jason Pierre-Paul was recently involved in a car accident. Fortunately, JPP was not seriously injured in the crash.
I heard JPP has a neck fracture?
