Darryl Dawkins, the former Philadelphia 76ers' player known for his legendary dunking abilities, has died, WFMZ reports. He was 58.

According to Dawkins' family, the NBA star died of a heart attack. "It is with great sadness that we share the passing of our beloved husband and father, Darryl Dawkins, who succumbed today to a heart attack. Darryl touched the hearts and spirits of so many with his big smile and personality, ferocious dunks, but more than anything, his huge, loving heart," the family said in a statement.

Dawkins began his NBA career in 1975, when he made history as the first player drafted directly from high school. He spent the majority of his career playing for the 76ers and the New Jersey Nets. Nicknamed the Chocolate Thunder by Stevie Wonder, Dawkins was famous for his dunks. In 1979, he shattered two backboards in separate games.
