New England Patriots

The Patriots drafted Cannon in the fifth round of the draft, with the 138th pick, acquired in a trade from the Houston Texans. Cannon's late selection in the draft is widely attributed to him being diagnosed with a non-Hodgkin lymphoma pre-draft. Weighing in at 358 pounds at the NFL Combine, Cannon is the heaviest player ever drafted by the Patriots, and the second-heaviest player in team history after nose tackle Ted Washington. (At TCU's pro day in March 2011, Cannon was measured at 349 pounds.) Although he played offensive tackle throughout his TCU career, the Patriots listed Cannon as an offensive guard when announcing the pick.

Cannon began the 2011 season on the Non-Football Injury list as he recuperated from his chemotherapy treatment, which took place during the NFL lockout. Cannon was activated to the 53-man roster after the Patriots' Week 10 game against the New York Jets, and saw his first snaps in the NFL at right tackle on the Patriots' final drive against the Kansas City Chiefs in Week 11. Cannon was selected as the Patriots' 2011 recipient for the Ed Block Courage Award.

Cannon played in all eighteen of the Patriots regular and postseason games of the 2012 NFL season, including one start in place of right tackle Sebastian Vollmer. After Vollmer went on injured reserve in late October of the 2013 season, Cannon started the rest of the season for New England at right tackle. Cannon began the year 2014 season as the Patriots starting left guard but struggled in the first three games and was moved back to his previous role as a swing tackle after rookie Bryan Stork took over as the starting center. On December 11 Cannon signed a two-year extension worth up to $9 million, including a $3.2 million signing bonus. On February 1, 2015, Cannon was a member of the New England Patriots when they won Super Bowl XLIX. In the 2015 season Cannon appeared in the fewest number of regular season games at 12, since his rookie season due to a toe injury but also started the most games of his career at eight.
