Italian tennis player Federico Luzzi died on Saturday after suffering from leukaemia, Italian news agency Ansa reported. He was just 28 years old.
He had fallen ill last Sunday with a fever that was initially believed to be some form of bronchopneumonia.
However tests at the San Donato hospital in his home town of Arezzo, in Tuscany, found that he actually had leukaemia.
He was transferred to the haematology department but slipped into a coma and died during resuscitation.
Both his mother and father were bedside when he died.
Luzzi was just inside the top 100 in the ATP world rankings but was best known for his part in a match-fixing scandal that saw him banned for 200 days.
