The death of the South African boxer Saturday was announced by family spokesman Ray McCauley.
Matlala died two days after Mandela, who attended Matlala's last bout in 2002. At the time, the boxer gave the former president one of his belts.
Matlala's former promoter, Rodney Berman, wrote on Twitter: "Another great fighter has died ... Go well little man, you'll be missed."
Standing just 4-foot-10 ½, Matlala's disregard for his size and ferocious punching speed made him one of South Africa's favorite athletes. During a 22-year career, he won flyweight and junior flyweight belts for the WBO as well as the IBA light flyweight title and WBU junior flyweight crown
