Today marks 50 years since British boxer Henry Cooper went toe-to-toe with the great Muhammad Ali - and became the first man to put him on the canvas.
Cooper and Cassius Clay, as the American was known then, battled it out during a non-title fight at Wembley Stadium on June 18, 1963.
The heavyweight bout saw 'Our 'Enry' floor Clay at the end of the fourth round before his rival fought back to win.
A year on from the fight, Ali memorably said that Cooper had "hit him so hard that his ancestors in Africa felt it."
The pair fought for a second time, at Highbury, in 1966 and this time Ali won more comfortably.
