George Foreman late in life may have been more recognizable for his innovative George Foreman Grills, but let’s be clear: knocking folks out was his true claim to fame. Before he became a smiling businessman selling lean, mean grilling machines, he was an all-time great boxer and a wrecking ball inside the ring—one of the most feared punchers in boxing history.

Whether as a young, unstoppable destroyer in the 1970s or the wise, patient knockout artist of his 40s, his ability to put opponents on the mat never faded. His career is a collection of jaw-dropping moments, but some knockouts stand above the rest—explosive, devastating, and era-defining.

Here are the five greatest knockouts of Big George’s legendary career, according to Top Rank Boxing.

5. Rocky Sekorsky (1987)
After a ten-year hiatus, Foreman returned to the ring pushing 40. In his fifth fight back, he faced off against a much younger Rocky Sekorski and put on a clinic, forcing the referee to jump in and end the fight in just the third round. Big George’s power had not aged a day.

4. Pierre Coetzer (1993)
Coetzer was durable, a battle-tested fighter who had taken beatings without folding. But against Foreman, there was no survival mode. This was Foreman in his second act—44 years old, methodical, patient, and still packing the kind of power that made retreat the only logical response.

3. Adilson Rodrigues (1990)
Rodrigues was quick, confident, and an opponent with a solid chin. But when Foreman landed, all of that went out the window. A right hand in the second round sent Rodrigues crashing to the mat, unconscious before he even hit the floor. Foreman didn’t need volume, just one perfect shot.

2. Gerry Cooney (1990) 
Cooney was a knockout artist himself, but Foreman’s power made all others feel ordinary. A brutal left hook wobbled Cooney, and a crushing right hand finished the job. Cooney went down in the second round, his career effectively ended. Foreman consistently proved that even against dangerous punchers, his power was still unmatched.

1. Michael Moorer (1994)
The perfect punch. At 45, Foreman landed a thunderous right hand that shattered Moorer’s defenses, and the heavyweight champion Moorer crumpled to the canvas in the 10th round. Foreman had just become the oldest heavyweight champion in history—a record that still stands to this day.

Rest in peace to one of the greatest to ever lace up their gloves.
