Lewis saw a diminished role in 2014, highlighted by his consecutive games with a catch streak snapped in week 5 against the Edmonton Eskimos. He was held without a reception in a regular season game for the first time since June 20, 2004, with the streak ending at 166. He posted career-low totals in receiving yards and failed to score a touchdown in any game of the season, also a career low. Despite the frustrating season, Lewis helped the Stampeders qualify for the 102nd Grey Cup, a game in which he set up Calgary's first touchdown with a 13-yard catch that brought the ball to the one-yard line. He won his second Grey Cup championship following the Stampeders' 20-16 win over the Hamilton Tiger-Cats. After 11 seasons with the Stamps, Lewis was not re-signed following the 2014 season, and became a free agent on February 10, 2015.
