Moses Malone, a three-time NBA MVP and Hall of Famer, died in his sleep Sunday at the age of 60, according to Fox News.

The 13-time All-Star died of an apparent heart attack, according to Fox26 Sports Director Mark Berman. He was scheduled to play in a golf tournament in Norfolk, Va., with fellow Hall of Famer Calvin Murphy, the report says.

Malone, who earned the nickname “Chairman of the Boards” for his rebounding skills, "won a title with the Philadelphia 76ers in 1983 and made the All-Star game 12 times in a row, from 1978-1989. During 21 seasons playing pro basketball, the 6-10 center averaged 20.3 points and 12.3 rebounds per game," the report says.

He was the first player to go pro directly from high school, the report notes, and made his debut during the 1974-75 season for the Utah Stars of the American Basketball Association. "He played the next season with the ABA’s Spirits of St. Louis before beginning an NBA trek through Buffalo, Houston, Philadelphia, Washington, Atlanta, Milwaukee and San Antonio," Fox News writes.

Malone led the NBA in rebounds per game in 1978-79 and every season from 1980-81 to 1984-85. In 2001 he was admitted into the Hall of Fame, the report says.
