On November 12, 1993, at UFC 1: The Beginning in Denver, Colorado, Brazilian jiu-jitsu representative Royce Gracie faced professional boxer Art Jimmerson in one of the most historically significant fights in mixed martial arts history. The bout was designed to answer one of the central questions behind the inaugural UFC tournament: which martial art was most effective in a real fight with minimal rules? It took only 2 minutes and 18 seconds for Gracie to provide an answer that would forever change combat sports.
Jimmerson entered the tournament as an accomplished professional boxer with more than 30 victories and a reputation for fast, accurate hands. Weighing approximately 196 pounds, he held nearly a 20-pound advantage over the lean, 176-pound Gracie. Confident in his boxing, Jimmerson famously stepped into the Octagon wearing only one boxing glove—his left glove remained on to protect his jab hand, while his right hand was left bare in hopes of improving his ability to grapple or land a knockout punch. The unusual decision earned him the nickname “One Glove” and became one of the defining images of early UFC history.
As soon as the fight began, Gracie calmly circled outside Jimmerson’s punching range. The boxer stayed light on his feet and looked for an opportunity to establish his jab, but Gracie showed little interest in exchanging strikes. Instead, he closed the distance almost immediately, secured a body lock, and effortlessly executed a takedown. The speed with which Gracie transitioned from standing to the ground caught Jimmerson completely off guard.
Once on the canvas, Gracie quickly advanced to a dominant mounted position. Rather than unleashing heavy punches, he relied on positional control, methodically isolating Jimmerson’s arms while maintaining relentless pressure with his hips and chest. Jimmerson, who had virtually no experience defending against Brazilian jiu-jitsu, struggled to create space or return to his feet. Every attempt to bridge or push Gracie away was neutralized by superior leverage and balance.
From mount, Gracie patiently threatened submissions while delivering occasional short strikes to force reactions. Jimmerson became increasingly uncomfortable beneath the suffocating pressure, realizing that his boxing skills offered no solution on the ground. Unable to escape and fearing a serious injury from an impending submission, he elected to tap the canvas with his free right hand without Gracie having to fully lock in a submission hold. The referee immediately halted the contest at 2:18 of the first round, officially recording the victory as a submission for Gracie. Some observers have described the finish as resulting from overwhelming positional pressure or a “smother,” though the official result is simply submission.
Although the fight lasted barely over two minutes, its impact on martial arts was enormous. Gracie had defeated a larger, accomplished professional boxer without absorbing meaningful damage or relying on striking. The bout demonstrated that grappling and ground fighting could completely neutralize an elite striker who lacked wrestling or submission defense. For many viewers, it was the first time they had witnessed Brazilian jiu-jitsu in action, and it immediately challenged long-held assumptions about which fighting styles were most effective.
The victory advanced Royce Gracie to the semifinals, where he submitted Ken Shamrock before later defeating Gerard Gordeau in the tournament final to become the first UFC champion. Jimmerson, meanwhile, returned to professional boxing and never competed in mixed martial arts again, but his memorable appearance wearing one glove remains one of the most iconic images in UFC history.
