Bare knuckle vs. gloved boxing: the rules and injury data
The two rulebooks agree on more than you might expect. The injury research is real but narrow, and one detail about who did the counting is worth knowing.
One clause in the Queensberry rules still reads like a shop order: "The gloves to be fair-sized boxing gloves of the best quality and new" (Wikipedia). New, every time. John Graham Chambers drafted the code in 1865, it was published in 1867 under the Marquess of Queensberry's name, and that sentence is roughly where gloved boxing and the bare-knuckle prize ring went separate ways.
I wanted to compare the two as they are regulated in the United States now, so I used the Association of Boxing Commissions' own documents for each rather than promoters' summaries. The differences turn out to be smaller than the names suggest in some places and larger in others. Our main BKFC explainer covers the promotion itself.
The rulebooks side by side
| Rule | Gloved pro boxing | Bare knuckle |
|---|---|---|
| Hands | 8 oz. gloves in lighter classes, 10 oz. from super welterweight up | No gloves; wraps stop one inch short of the knuckles |
| Gauze limit | 20 yards per hand | 12 yards per hand |
| Tape limit | 8 feet, up to 1.5 inches wide | 10 yards, up to 1 inch wide |
| Round length | 3 minutes, 1-minute rest | 2 or 3 minutes, 1-minute rest |
| Longest bout | 12 rounds for men, 10 for women | 6 rounds and 18 minutes of fighting |
| Standing eight count | None | None |
| After a knockdown | Mandatory eight count | Mandatory eight count |
Two things surprised me. The bare-knuckle rules allow more tape by length, 10 yards against 8 feet, while allowing less gauze (ABC guidelines; ABC bare-knuckle rules). And the counting rules are identical: no standing eight count in either sport, and a mandatory eight after every knockdown (ABC boxing rules). The big structural gaps are the gloves themselves and the length of the fight: a bare-knuckle bout can run at most half the rounds of a 12-round gloved fight.
The rule-maker who helped popularize gloves
Here is the irony I enjoyed most. Jack Broughton, whose 1743 rules BKFC borrows for its scratch lines, is also credited with popularizing boxing gloves, though they did not become standard until the mid-19th century (Wikipedia). The patron saint of bare knuckle fighting helped put the padding on.
The switch at the top of the sport came fast once it came. John L. Sullivan won the last bare-knuckle heavyweight title fight in 1889, then lost the championship to James J. Corbett in New Orleans on September 7, 1892, under Queensberry rules with gloves on (Wikipedia).
What the injury studies actually measured
The comparison most people want is about injuries, and here the evidence needs careful handling. The best-known data set is a 2021 paper in The Physician and Sportsmedicine by Don Muzzi and colleagues, with authors from NYU Langone Health (DOI). It covered every state-sanctioned professional bare-knuckle bout from June 2018 through November 2020: 141 bouts and 282 fighters.
- 105 of the 282 fighters had at least one injury, with 123 injuries in total.
- 98 were lacerations, 80 of them facial, needing about six sutures each on average.
- Fractures included 8 in the hand, 6 nasal, 2 orbital and 2 dental.
- 8 fighters, 2.8 percent, had concussions with symptoms, and 5 hospital transfers were needed, 3 of them for traumatic brain injuries.
The authors concluded that cuts and hand fractures were the most frequent injuries and that concussions were relatively uncommon compared with other injuries. Read that sentence closely. It compares concussions with cuts inside bare-knuckle fighting. It is not a head-to-head trial against gloved boxing, and I would not treat a low count of diagnosed concussions as proof of low brain risk. One small oddity, too: the abstract gives 17 fractures, while its own breakdown adds up to 18.
A 2022 follow-up in the Journal of Oral and Maxillofacial Surgery looked at 301 matches from June 2018 to March 2022 and found 211 facial injuries among 177 fighters, 184 of them cuts. Traumatic brain injury was associated with knockouts, which mostly came in the first and second rounds (DOI). On that paper, Muzzi's affiliation is listed as chief medical officer of Bare Knuckle Fighting Championship. That does not make the numbers wrong; being ringside for every bout is exactly how complete data gets collected. It is still worth knowing who did the counting.
Chambers asked for new gloves of the best quality. The bare-knuckle rulebook asks for bare skin an inch past the tape. Written 159 years apart, both are answering the same stubborn question about how much protection a fist should carry, and neither has settled it.
