What happened: Johnny Walker credited competing at his natural weight for easing his physical preparation ahead of UFC Vegas 124, stating that life in the division is easy without extreme weight cuts. Walker moved up to the division in October, securing a first-round knockout at UFC 332 in his heavyweight debut.

Why it matters: The transition to heavyweight removes the grueling cuts that previously affected Walker's endurance and durability at 205 pounds. Establishing consistency in the division offers a path toward title contention as he looks to build on his initial success in the higher weight class.

What to watch: Walker headlines UFC Vegas 124 against Waldo Cortes-Acosta at the UFC Apex.
