Muhammad Ali vs. Bob Foster, billed as The Sound and the Fury, was a professional boxing match contested on November 21, 1972, for the NABF heavyweight championship.

Ali became less aggressive in the sixth round and most of the seventh, with both fighters throwing few power punches and landing additional jabs that worsened each other's cuts.

Foster got up and landed a few straight rights in return but, as earlier, was unable to do any damage; Ali mocked his opponent by faking being staggered before knocking him down a sixth time with a left hook shortly before the end of the round.

Foster rose but failed to beat the referee's count, ending the fight in an eighth-round KO for Ali.

[12] Foster would return to the light heavyweight division while Ali would next face brit Joe Bugner.
