Williams (ribs) practiced without any limitations Thursday, Sal Capaccio of WGR550 reports.
Williams has now successfully practiced in consecutive days and it appears the 22-year-old will be available for Sunday's matchup with the Ravens. Listed as the No. 4 running back on the Bills' official team depth chart, the rookie is unlikely to see a ton of action with the offense Sunday, with LeSean McCoy, Mike Gillislee and Reggie Bush also on hand.
