Stripped of his heavyweight title in 1967, who did Muhammad Ali regain the heavyweight championship against?

Muhammad Ali ( born Cassius Marcellus Clay Jr.; January 17, 1942 – June 3, 2016) was an American professional boxer and activist. He is widely regarded as one of the most significant and celebrated sports figures of the 20th century. From early in his career, Ali was known as an inspiring, controversial, and polarizing figure both inside and outside the ring.

After Ali's title defense against Zora Folley on March 22, he was stripped of his title due to his refusal to be drafted to army service. His boxing license was also suspended by the state of New York. He was convicted of draft evasion on June 20 and sentenced to five years in prison and a $10,000 fine. He paid a bond and remained free while the verdict was being appealed.

The Rumble in the Jungle was a historic boxing event in Kinshasa, Zaire (now Democratic Republic of the Congo) on October 30, 1974 (at 4:00 am). Held at the 20th of May Stadium (now the Stade Tata Raphaël), it pitted the undefeated world heavyweight champion George Foreman against challenger Muhammad Ali, a former heavyweight champion. The attendance was 60,000. Ali won by knockout, putting Foreman down just before the end of the eighth round becoming the heavyweight champion for a second time. It has been called "arguably the greatest sporting event of the 20th century".
