Smith was eventually drafted sixth overall by the Cincinnati Bengals. He was the first Alabama offensive lineman selected in the first round of an NFL Draft since Chris Samuels in 2000. With run-blocking being his premier quality, Smith was projected to start at right tackle for the Bengals. However, after a 30-day contract impasse, Smith missed all of training camp and three preseason games, before eventually signing his contract on August 30, 2009. It is believed that Smith was looking for a five-year, $40 million deal, but was signed to a four-year contract with only $21 million guaranteed. The Bengals also had an option in his contract after the 2010 season to make it a six-year, $42 million agreement.
