Bare Knuckle Fighting Championship (BKFC) is the fastest-growing combat sport in the world, but for new fans, the ruleset can be confusing. How are fights scored? What separates a knockdown from a knockout? This guide breaks down everything you need to know about BKFC rules and scoring.

The Basics: What Is BKFC?

Founded by David Feldman in 2018, BKFC is a sanctioned combat sport where fighters compete without gloves or hand wraps — only approved hand tape on the wrists below the knuckle line. The promotion has grown rapidly, attracting high-profile crossover fighters from boxing and MMA.

Round Structure

BKFC bouts follow a consistent structure:

• Non-title fights: 5 rounds, 2 minutes each
• Championship fights: 7 rounds, 2 minutes each
• Rest periods: 1 minute between rounds

The shorter rounds are intentional — bare knuckle combat is intense and exhausting at a pace that makes two-minute rounds feel significantly longer than they do in boxing.

BKFC Scoring Criteria

BKFC uses the standard 10-point must system familiar to boxing fans, with some additional criteria specific to the bare knuckle format. Judges score each round on a 10-point scale, with the round winner receiving 10 points and the loser receiving 9 (or fewer in the case of knockdowns or dominant performances).

Judges evaluate fighters on the following criteria:

• Clean strikes landed: The most important factor. A clean punch that lands on the face or body scores higher than glancing blows.
• Effective aggression: Moving forward while landing is rewarded; wild rushing is not.
• Defense and ring generalship: Slipping, rolling, and controlling distance count, though less than clean offense.
• Knockdowns: Any knockdown in a round results in a 10-8 score for that judge, regardless of other activity in the round.

The Scratch Line

One of BKFC’s most distinctive features is the scratch line — a small line in the center of the ring where both fighters must start each round, toe-to-toe, within striking distance. This ensures engagement from the first second of every round and dramatically increases the pace and intensity compared to boxing or MMA.

Fighters who repeatedly refuse to engage from the scratch line can be penalized by the referee.

What Counts as a Knockdown?

A knockdown is called when a fighter touches the canvas with any part of the body other than the feet as a result of a legal strike, is held up by the ropes in a helpless position, or is rendered visibly hurt at the referee’s discretion. After a knockdown, the standing fighter goes to a neutral corner while the downed fighter receives a mandatory eight count.

Ways a Fight Can End

BKFC fights can end via KO, TKO (referee stoppage or corner towel), unanimous decision, split decision, majority decision, draw, or disqualification. Unlike boxing, there is no standing eight count — a fighter must beat the mandatory count from a knockdown to continue.

Common Fouls

BKFC is a punches-only, stand-up sport. The following are prohibited: strikes to the back of the head or spine, eye gouging, headbutts, ground-and-pound (striking a downed opponent), kicks, elbows, and knees. Clinch striking is heavily restricted. Fouls result in point deductions, and repeated fouls lead to disqualification.

Weight Classes

BKFC currently sanctions Strawweight (115), Flyweight (125), Bantamweight (135), Featherweight (145), Lightweight (155), Welterweight (170), Middleweight (185), Heavyweight (265), and Super Heavyweight (265+).

The Bottom Line

BKFC combines aggression, toughness, and technical striking in a uniquely raw format. Once you understand the scoring system and rules, every exchange at the scratch line carries a new level of meaning. Main Card Media covers BKFC events, results, and fighter news throughout the year.
