The octagon may be the arena of choice for the Ultimate Fighting Championship, but the growing mixed martial arts promotion company now has its eye on hiring some high-profile antitrust lawyers for a fight in the courtroom.

Slapped with a $100 million antitrust suit this week by a group of ex-fighters backed by a formidable team of plaintiffs lawyers, the UFC and its Las Vegas-based parent company Zuffa LLC have commenced a beauty contest involving several top firms flexing their legal muscles in an effort to secure the lucrative defense work against claimants threatening to knockout the upstart organization in a federal court.
