Bare Knuckle Fighting Championship

On August 20, 2021, BKFC was involved in controversy after the death of boxer Justin Thornton at BKFC 20.[12] Justin Thornton died as a result of spinal injury suffered during his BKFC debut.[13] Thornton had been on a five-fight losing streak ahead of the fight. The matchmaking and regulations were criticised following the news on social media and by UFC president Dana White.[14]

Initially, BKFC pay-per-view bouts were carried worldwide via FITE TV. On July 24, 2020 it was announced that starting on August, DAZN will be streaming BKFC events.[15] In February 2023, Fite announced to include all events to its Fite+ subscription service.[16]

BKFC holds all bouts in a circular four-rope ring, referred to as the "Squared Circle". This ring incorporates elements of historical bare knuckle fighting by containing two scratch lines, three feet apart and in the middle of the ring. These scratch lines are based on the Broughton Rules, which governed bare knuckle fighting in the 19th century. It is a requirement that each fighter must start each round with their front foot on their scratch line. This is referred to as “Toe the Line”, and it is an instruction given to the fighters at the beginning of each round, followed by "Knuckle Up" which signals the beginning of the round.[17]
