These dramatic, ringside pictures expose the no-holds-barred world of British bare-knuckle boxing, in which opponents fight for cash prizes.
The incredible photos uncover the bloodthirsty events, where brutal knockouts bring many bouts to a premature end.
They were taken at the Bare Fist Boxing Association's Blood Sport 2 event, which was held at an old cotton mill in Bolton, Greater Manchester.
Fights earned the ire of a councillor in the town, but organisers insist the scraps are legal, although the sport remains unregulated due to there being no established licensing body.
Top bare-knuckle fighters can earn up to £50,000 in just one fight and the association is set to hold another event on St Patrick's Day.
Bare Fist Boxing Association spokesman Andrew Bowling, 33, says organised fights guard against illegal one and argues the fights are no more violent than Mixed Martial Arts. And unlike Formula 1 and darts competitions, the brawlers have no plans to ban their walk-on girls.
