Nate Diaz has filed a lawsuit against Fanmio and its founder Solomon Engel, claiming he is owed $9 million for his boxing match against Jorge Masvidal on July 6. Diaz was reportedly promised a total of $10 million for the fight but received only $1 million upfront. The lawsuit, filed in U.S. District Court in Miami, alleges fraud and breach of contract. Engel has reportedly told Diaz's representatives that he cannot pay the remaining amount due to potential financial losses and bankruptcy. Diaz is seeking to recover the unpaid portion of his purse through legal action. The agreement was both verbal and written.
