With running back Rashard Mendenhall set to undergo an MRI exam to determine the extent of his knee injury, it would seem like a time the Arizona Cardinals would be looking to potentially add another rusher. However, despite Mendenhall’s knee ailment, the Cardinals are shopping former second-round pick Ryan Williams, according to Jason La Canfora of CBS Sports.

Cardinals head coach Bruce Arians was raving about Williams over the offseason. However, his surgically-repaired knee gave him issues throughout training camp, causing him to make his first preseason appearance during the team’s third exhibition contest.

If this report is true, the Cardinals would be indicating that they’d be willing to go with a committee of Alfonso Smith and rookies Stepfan Taylor and Andre Ellington behind Mendenhall.

NFL.com mentions that Williams has ties to the Chargers and Jets based on his connections with former front office executives and head coach Ken Whisenhunt. However, it’s unclear if any teams are interested in the running back.
