A lawsuit against famed boxing promoter Don King seeks more than $3 billion, alleging King falsely denied being involved in an anniversary event for his historic “Rumble in the Jungle.”

BYD Sports and BYD Management, two limited liability companies, filed the complaint in federal court against King, 93, last month, alleging defamation, tortious interference and fraud.

According to the complaint, BYD CEO Cecil Miller alleges he was working with King for more than a year on a “Rumble in the Jungle 2” before Don King Productions issued a cease-and-desist letter claiming no affiliation with the event.

Don King Productions did not immediately respond to a request for comment. An attorney for King or the company is not listed in the court record.
