Court records show Haider Zafar will plead guilty to five counts of wire fraud, each of which carries a maximum 20-year prison sentence.
Prosecutors say Zafar defrauded players Mike Miller, James Jones and Rashard Lewis in 2013 by promising to invest their combined $7.5 million in various business opportunities.
Instead, prosecutors say Zafar kept the money and used some of it to buy a $1 million, three-season Heat ticket package.
Zafar pleaded guilty in February in Ohio federal court in an unrelated $10 million land-buying swindle. He will formally plead guilty in the Florida case after it is transferred to Ohio.
