Former heavyweight boxer Ernie Terrell, who was famously defeated by Muhammad Ali, has died, aged 75.

Terrell passed away on Tuesday (16Dec14) at his home in Chicago, Illinois. He had been suffering from dementia.

The towering boxer, who stood at six foot six inches tall (1.98 metres), is best known for his humiliating defeat in a bout with Ali while defending his World Boxing Association (Wba) title and five-year winning streak in 1967.

Terrell famously refused to call his opponent by his adopted name Muhammad Ali and persisted to call him his birth name Cassius Clay, which angered the boxing legend ahead of their match in Houston, Texas.

In revenge for Terrell's remarks, Ali brutally punished him through 15 rounds, and Terrell's eyes were permanently damaged. He retired seven years later (73), with 46 wins and nine defeats to his name.

Alongside boxing, Terrell enjoyed a music career with Ernie Terrell and the Heavyweights, a group which once performed on America's The Ed Sullivan Show. His younger sister Jean, who sang back-up vocals, replaced Diana Ross as lead singer of The Supremes in 1970.

After his boxing retirement, Terrell became a music producer in Chicago and ran a cleaning company.
