Williams is tending to a hamstring injury, which is expected to hold him out of the final week of Cardinals OTAs, Kyle Odegard of the team's official site reports.

Analysis:

Williams' absence from practice appears to be a precautionary measure, but the true extent of the injury will be clear if he misses any of next week's mandatory minicamp. Currently, he's among a cadre of runnings backs vying for the primary backup role to Andre Ellington -- also, Stepfan Taylor, Marion Grice, and 2015 third-round pick David Johnson -- with any missed time a hindrance in that endeavor. No matter, Williams showed himself well in a five-game sample with the Cardinals last season, racking up 269 on 63 carries, which was good for 4.27 YPC.
