The Arizona Cardinals have a considerable amount of depth at running back, and it appears they may be trying to thin the herd a bit via a trade.

According to CBSSports.com’s Jason LaCanfora, the team is shopping third-year pro Ryan Williams.

Williams, a 2011 second-round pick, has battled various medical setbacks, has been the subject of trade talks.

Indeed, Williams has struggled to stay healthy since being taken in the second round of the 2011 NFL Draft, as the former Virginia Tech star suffered a ruptured patella tendon in the first preseason game of his rookie year and then a season-ending shoulder injury Week 5 of last season.

And given that the team replaced its coaching staff in January, this offseason stood as an important one for Williams’ future in Arizona. However, he’s battled knee soreness since early in training camp, and finally saw the field for the first time Saturday against the San Diego Chargers.

For his career, Williams has tallied 164 yards on 58 carries, as well as 44 yards on seven receptions.
