Professional career
Chicago Bears
Williams was drafted by the Bears 14th overall in the 2008 NFL Draft. On July 23, 2008, it was announced that he had signed a five-year contract with the Bears. Williams missed the camp's first weekend after sustaining a minorback injury. He was later diagnosed with separate injury, a herniated disc, which required minor surgery to repair. Williams started taking part in conditioning and work-out drills in September. On November 2, 2008, he made his professional debut on the special teams in a win against the Detroit Lions. Williams was a starter in 2009, and played at right tackle to accommodate Orlando Pace, whom the team acquired via free agency on April 2, 2009. Smith eventually moved Williams back to left tackle after Pace was faced with inconsistent play and injuries. His first major test was to protect Jay Cutler's blindside against the highly touted Baltimore Ravens defense. The following week, he was paired against Jared Allen of the Minnesota Vikings, one of the League's top defensive lineman and pass rushers. Williams' prevented Allen from sacking Cutler, as the Bears beat the Vikings, 36–30. Williams started the 2010 season as the Bears starting left tackle. However, he was injured early during the team's second game against the Dallas Cowboys. Williams spent the next several weeks nursing a hamstring injury and missed three games. Upon recovering from his injury, Mike Tice, the team's offensive line coach, decided to move Williams to the left guard position. Williams was released by the Bears on October 16, 2012.
St. Louis Rams
Williams signed with the St. Louis Rams on October 22, 2012. He re-signed with the team on April 1, 2013 for 2.75 million on a one-year contract.
Buffalo Bills
On March 12, 2014, Williams signed a four-year, $13.5 million contract with the Buffalo Bills. The deal includes $5.5 million in guaranteed money. His contract was terminated after a failed physical on July 28, 2015.
