Dixon is also known for being wrongfully convicted in May 2003 of molesting an underage girl while he was in high school. That charge was overturned by the Georgia Supreme Court, while his conviction for statutory rape was sustained.
Dixon was a grade A student at Pepperell High School and excelled on the football field to the point where he had been offered a full scholarship at Vanderbilt University, but he was accused of molesting an underage student, was tried and convicted and therefore was unable to attend Vanderbilt.
Upon his release from prison Dixon enrolled at Hampton University in Hampton, Virginia with a football scholarship. At Hampton, Dixon played at defensive end and defensive tackle, and was on the all Mid-Eastern Athletic (MEAC) conference team during his junior and senior seasons.
On September 5, 2010, Dixon was claimed off waivers by the New York Jets. An exclusive rights free agent, Dixon was signed to a one-year contract on January 26, 2011. Dixon was released on September 1, 2012. He was re-signed to the active roster on September 4. Dixon was released by the team on September 24, 2012.
Kristie Brown alleged that on February 10, 2003 Dixon forced her to have sex, taking her virginity. She has stated that contrary to Dixon's supporters' belief she was never Dixon's girlfriend and although they shared classes, they barely knew each other. The jury acquitted Dixon of rape, battery, assault and false imprisonment but because Brown was only 15 at the time of the incident found him guilty of statutory rape and aggravated child molestation. Because of this Dixon was convicted at the mandatory amount under Georgia law, 10 years imprisonment. Ironically, if he had been found guilty of rape, he would have faced a much less severe punishment.
The Georgia Supreme Court overturned Dixon's conviction and he was released May 3, 2004. The court let his conviction for misdemeanor statutory rape stand. After Dixon's release both he and Brown appeared on The Oprah Winfrey Show in an attempt to clarify their stories.
