Fighter Bio


Sean "The Cannon" Gannon is a Boston, Massachusetts police officer, and mixed martial arts (MMA) fighter, who gained notoriety on the Internet after video of him fighting Kimbo Slice in a bare-knuckle fight became widely distributed.

This notoriety lead him to be the focus of a front page article on the Boston Herald, and an internal Boston Police investigation into his off-hours activities. The incident also caught the attention of the Ultimate Fighting Championship, who then promoted a fight between him and professional mixed martial arts fighter Branden Lee Hinkle. Gannon lost to Hinkle at UFC 55. Currently, Gannon has a professional MMA record of 1-1 and hasn't fought since losing to Hinkle.

Gannon is also a former Golden Gloves boxer and a state judo champion.
