The Cardinals have released running back Kerwynn Williams, as Josh Weinfuss of ESPN.com tweets. In his place, the team has promoted tight end Hakeem Valles from the practice squad. 
Williams was signed earlier this week after running back Chris Johnson was placed on IR. However, the reunion was short lived. With Williams out of the picture, the Cardinals now have one-time starter Andre Ellington and Stepfan Taylor behind David Johnson.
Valles, soon-to-be 24, came to the Cardinals this year as an undrafted free agent out of Monmouth. The 6’5″, 260 pound athlete was among the team’s final cuts before the 53-man deadline but quickly agreed to join Arizona’s practice squad.
