Cunningham accepted an athletic scholarship to attend the University of Florida in Gainesville, Florida, where he played for coach Urban Meyer's Florida Gators football team from 2006 to 2009. As a freshman in 2006, he played in seven games as a defensive end. He went on to start 13 games at defensive end as a sophomore in 2007, recording 64 tackles, 6.5 sacks, and 12 tackles for a loss. During his 2008 junior season, Cunningham started 13 of 14 games and finished second on the team with six sacks, while also picking up ten tackles for a loss and three forced fumbles. As a senior in 2009, Cunningham started 12 games, and missed two with injuries. He finished with 34 tackles and ranked second on the team with seven sacks, while also finishing fifth in the conference with 12 tackles for a loss. Following his junior and senior seasons in 2008 and 2009, he was a second-team All-Southeastern Conference selection, and he completed his college career with five forced fumbles and 19.5 quarterback sacks—tied for tenth on the Gators' career sacks record list with teammate Carlos Dunlap. During his time as a Gator, the team won two SEC Championship Games and two BCS National Championship Games.
Cunningham was drafted by the New England Patriots in the second round of the 2010 NFL Draft. He signed a four-year contract on July 24, 2010.

Personal life
Cunningham, along with U.S. Olympic track hopeful Xavier Carter and former Gator Jonathan Demps, was arrested in 2007 after an altercation with a Jimmy John's employee. The group became "verbally abusive, struck the employee with empty soda cans and a sandwich, and fled the store" after the clerk asked them to pay for a bag of chips. In late December 2014, Cunningham was charged with multiple counts in Union County, New Jersey.
