Muhammad Ali vs. Brian London was a professional boxing match contested on 6 August 1966, for the WBC, NYSAC, and The Ring heavyweight championship.

[2][3][4][5][6] Speaking before the bout London appeared unfazed by Ali's typical taunts, saying "Clay insult me ….

He would conceded that the champion would be the superior boxer but warned that: "Clay may cut me, out-box me, or even beat me.

Ali bouncingly circled continually, whilst London tracked doggedly after him for the first two rounds seemingly with a strategy of trying to land a single knock-out punch to the American champion.

On coming out for the 3rd Round London displayed a patent degree of hesitation to come forward to engage, and Ali sensing this advanced to the attack flashly, penning him back into a corner and throwing a 12-punch combination in 3 seconds in a showboating display of speed and athleticism, but with a suspicion of Ali holding back, with few of the blows actually connecting or possessing weight behind them, and the one blow that did (the 10th) being just enough to knock London down and end the fight.
