Smith missed all of the 2014 preseason while rehabbing from a concussion, but was able to start in the season opener game. He played and started in nine games played on the season. He was inactive for games 9-10, and was placed on Reserve/Injured list on November 25, following a triceps injury suffered in week 11. He played a key role in the Bengals pass protection for the nine games he played, helping the Bengals finish the season ranked third in the NFL in fewest sacks allowed with 23 and in least sack yardage allowed (123 yards). He was part of an offensive line that allowed no sacks in the first three weeks of the season for first time in franchise history. He was credited by coaches with the key block on Giovani Bernard’s 89-yard touchdown run, the second-longest in Bengals history, on October 12 against the Carolina Panthers. He helped pave the way for three one-yard touchdown runs in goal line situations in week 8 against the Baltimore Ravens, including the game-winning touchdown by Andy Dalton on a fourth-and-one situation late in the fourth quarter.
