Light heavyweight contender Johnny Walker has discussed his intentions to compete in the heavyweight division. Walker revealed he has sparred with Francis Ngannou and felt comfortable working with him despite a 20-kilogram weight difference while on his diet. He believes he would perform much better at heavyweight because the weight cut negatively impacts his training. Walker explained that during his diet he experiences dizziness and low energy due to lack of carbohydrates. The move would represent a significant shift in his UFC career trajectory.
Brazilian light heavyweight Johnny Walker has publicly discussed plans to move up to the heavyweight division, signaling a potential major shift in his UFC career.
Walker, 34, currently sits ranked eleventh in the light heavyweight division with a professional record of 22-10-0. Representing SBG Ireland, the six-foot-six, 208-centimeter striker carries a remarkable 82-inch reach and lands an impressive 4.06 significant strikes per minute at a 55 percent accuracy rate. He revealed that the demands of cutting weight are taking a real toll, describing how carbohydrate restriction during his diet leaves him dizzy and drained of energy, hampering his preparation and overall training quality.

To test his viability at the heavier weight class, Walker said he has sparred with former heavyweight champion Francis Ngannou and felt comfortable doing so despite a reported 20-kilogram weight gap between them while Walker was still in diet mode. The experience, Walker indicated, gave him confidence that he could perform at an even higher level if he no longer had to endure the punishing cut.
Ngannou, 38, carries an 18-3-0 record and holds a pound-for-pound ranking of twelfth. The Cameroonian stands six-foot-four with an 83-inch reach, and his reputation as one of the most physically imposing heavyweights in combat sports history makes Walker's comfort in those sparring sessions a meaningful data point.

Why it matters
- Walker already possesses elite heavyweight dimensions at six-foot-six with an 82-inch reach, meaning the physical transition would be natural.
- A move to heavyweight at 22-10-0 could reinvigorate his career trajectory and open a fresh set of matchups.
- His striking volume and accuracy numbers could translate into significant heavyweight firepower if training is no longer compromised by weight cuts.
- The light heavyweight division loses a ranked contender, potentially reshuffling the top-fifteen picture.
