Muhammad Ali vs. Leon Spinks was a professional boxing match contested on February 15, 1978, in Las Vegas, Nevada, for the WBA, WBC, and The Ring heavyweight championship.

[1] After his unanimous decision victory against Earnie Shavers, Muhammad Ali decided to face 1976 Olympic Gold medalist Leon Spinks, knowing that he would have to face Ken Norton for the fourth time or lose his WBC belt, after the No.

Spinks was later stripped of his WBC heavyweight title on March 18, 1978, for refusing to fight No.

Instead, Spinks signed for a rematch with Ali at the Louisiana Superdome in New Orleans.

The rematch took place on September 15, 1978, for the World Boxing Association and Lineal Heavyweight Champion titles.
