The Cardinals have parted ways with 2011 second-round pick Ryan Williams, tweets Darren Urban of AZCardinals.com. Williams is one of four players let go today by the Cardinals, who also cut center John Estes, linebacker Kenny Rowe, and tight end Brett Brackett, according to Urban (Twitter link).

Williams, 24, was selected 38th overall in 2011, but could never get healthy enough to become a contributor for the Cardinals. After missing his rookie season, Williams accumulated 164 yards on 58 carries in 2012, then was injured for the entire 2013 season as well. Arizona creates a little over $1MM in cap savings by letting go of the young running back.
