PFL co-owner Donn Davis has made a bold claim about the cost of the promotion's "Battle of the Giants" pay-per-view event. The card is headlined by a heavyweight title fight between champion Renan Ferreira and former UFC champ Francis Ngannou on Oct.

Blockbuster trades in MMA don't happen like in other sports, and free agency only usually occurs when a fighter is either on the decline or a prospect is ready to rise up. Yet, many fighters are at a crossroads.

According to PFL executive Donn Davis, next month's card headlined by Francis Ngannou vs. Renan Ferreira will be quite expensive.

PFL founder and president Donn Davis wants to make it clear, his organization and the UFC are the two MMA promotions that make of a global duopoly.
