Watch Muhammad Ali vs. Sonny Liston II (1965) Official Trailer

Because of the unexpected ending of the first bout, the World Boxing Council ordered a rematch, this time with Liston as challenger. The World Boxing Association disagreed, as immediate rematches were against its rules, and stripped Ali of his title. Originally scheduled for the Boston Garden in Boston, Massachusetts in November 1964, the fight was postponed six months when Ali needed emergency surgery for a strangulated hernia.
