Williams (quadriceps/ribs) is expected to play Sunday against the Giants, Adam Schefter of ESPN reports.
Williams was listed as questionable on the official injury report when he was able to upgrade to a limited practice Friday after sitting out back-to-back sessions to begin the week. Though it sounds like he's not 100 percent, Williams should operate as the Cardinals' lead back if he plays. He draws an attractive matchup against a Giants defense that has surrendered 117.9 rushing yards per game and six rushing touchdowns over the past seven contests.
