At Caesars Palace in May 1983, two men walked into the ring for a non-title super-featherweight contest shrouded in courtroom squabbles, promoter politics, and the uncertainty of whether it would even take place. What followed was a savage, sprawling battle that has since been etched into boxing folklore.

Bobby Chacon, officially the WBC champion but unable to defend his crown due to legal wrangling with Don King, met his old rival Cornelius Boza Edwards, the Ugandan southpaw ranked the organisation’s leading contender. Three days before the fight, a Los Angeles judge attempted to halt proceedings with an injunction, only for a California appellate panel to overturn it hours later. The bout went ahead—but strictly as a non-title affair. If the drama outside the ring was turbulent, it was nothing compared to what unfolded once the opening bell sounded.

From the first exchanges it was clear that neither man intended to pace himself. Boza Edwards sprang forward with crisp, accurate combinations, while Chacon—ever the entertainer—chose to trade rather than evade. In the second round Edwards was floored, but moments later Chacon’s own face was split open. Within minutes he carried gashes above both eyes, damage which would haunt him throughout the contest.

The third saw Chacon dropped again, a flash fall as he sought to counter off the ropes. Instead of retreating, he pressed on, slinging back hooks with reckless defiance. The pair swapped knockdowns and momentum like gamblers pushing chips across a table, the fight swaying constantly and violently.

As the rounds wore on, the punishment accumulated in frightening quantities. Blood streamed from Chacon’s face, his vision compromised, his nose repeatedly targeted. Referee Richard Steele called in ringside doctor Flip Homansky several times to examine the champion, and twice the verdict seemed on the verge of ending Chacon’s night. Each time, Chacon insisted on continuing, shaking his head with stubborn pride.

By the middle sessions, Boza Edwards looked in complete command. His output never dipped, his straight punches slicing through Chacon’s worsening wounds. Many at ringside wondered how long the Californian could withstand the onslaught. His corner told him bluntly that he had only one more round to save himself.

And somehow, astonishingly, he did.

Chacon summoned a late revival reminiscent of his most dramatic victories. As Edwards’ legs began to betray the sheer volume of work he had produced, Chacon surged forward. In the twelfth, with both men exhausted, he hurled a right hand that sent Edwards sprawling. The Sport Pavilion erupted. Edwards rose, but he never fully recovered his footing, slipping and stumbling under the weight of fatigue as Chacon chased desperately to finish the job.

The final bell ended one of the most punishing contests ever staged in the division. When the judges returned scores of 115–113, 117–111 and 115–112, all for Chacon, the decision reflected the champion’s astonishing refusal to surrender.

In one of boxing’s most unforgettable battles, Bobby Chacon defeated Cornelius Boza Edwards in a Ring Magazine Fight of the Year.
