Chris Sarro was the first fighter from New England to sign a contract with the largest bare-knuckle organization in the world today, the Bare Knuckle Fighting Championship (BKFC). He began his professional fighting career on September 7, 2019, in Orono, Maine, competing for the Lewiston, Maine-based Mixed Martial Arts promotion New England Fights. In his debut match, Sarro delivered a stunning knockout to the heavily favored veteran Ras Hylton (4-2) just 67 seconds into the first round, using a single counter right hand in their Cruiserweight co-main event. This remarkable victory catapulted him into the spotlight, and shortly afterward, he signed a multi-fight contract with BKFC.
