Chances are you'll have heard of Muhammad Ali's grandson, Biaggio Ali-Walsh, who last year racked up some massive stats for his high school football team.
Ali-Walsh was turning heads on the American football field as a three-star running back for Bishop Gorman in Nevada - earning scholarship offers from UNLV and Louisville.
He was the standout player in Bishop Gorman's sixth straight league championship, scoring 10 touchdowns and running almost 600 yards from just 49 carries and racking up one of the fastest 40-yard dashes in the USA.
But Biaggio's younger brother, Nico, is keen to follow in his grandfather's shoes more literally. A talented amateur boxer, last year he revealed his dream is to become World heavyweight champion like his grandfather.
Considering he only recently became a teenager, he has a long way to shake up the world like 'The Greatest', but he certainly shook up his opponent with two booming overhand rights on an amateur card two nights ago.
(Ali-Walsh wears white, and the proper action begins at 4:00).
Was that a little 'Ali vs Liston' pose Nico did when his opponent was floored?
Also, bizarrely, Flava Flav of hip-hop group Public Enemy appears to be his groupie. But we wonder who his biggest fan is?
