James “Sugar Man” Walker is a British heavyweight bare-knuckle fighter whose route to BKFC began with amateur MMA. He competed in the amateur ranks from 2012 through 2015, then spent roughly a decade away from competition before returning to combat sports as a professional in 2025.

Walker made his BKFC debut against Jan Sulecki at BKFC Fight Night Newcastle in February 2025, earning a decision victory in his first fight back. He added a KO win over Kaseem Saleem at BKFC Fight Night Newcastle: Terrill vs. McFarlane in March 2026, bringing his promotional record to 2-0. At 6'6" with an 81-inch reach, Walker is an imposing presence in the heavyweight division and is scheduled to meet Dan Boyle at BKFC Fight Night Newcastle on August 1.

Rather than charging forward recklessly, Walker uses measured pressure and purposeful volume. BKFC has highlighted his ability to make his punches count—even when an opponent has landed more overall shots—suggesting a composed heavyweight who favors accuracy, patience, and impactful exchanges over wasted offense.
