Bare Knuckle Fighting Championship is geared up for its fourth event on February 2, 2019. This time, the promotion is headed to Cancun, Mexico for team U.S.A. vs. team Mexico. There are quite a bit of notable MMA fighters on the billing, such as Chris Lytle, Leonard Garcia, Joe Riggs, Bec Rawlings and more. Before Bare Knuckle FC 4 heads south of the border, Bloody Elbow caught up with the promotion’s founder/CEO David Feldman to discuss the company’s beginnings as well as the sport’s unique ‘toe the line’ feature. Feldman also explains why he thinks so many MMA fighters flock to Bare Knuckle, and whether or not we’ll see the return of bare knuckle MMA.
