Johnny Walker is a Brazilian striker and the UFC's No. 12-ranked heavyweight, moving up from light heavyweight to make just his second walk at the bigger weight. Eighteen of his 23 career wins are knockouts, built on freakish athleticism and flying attacks, and he arrives off a KO of Mick Parkin at UFC 332 in October 2026. He steps into the Nov. 7 main event on short notice against Waldo Cortes Acosta after the card's original headliners, Sean Brady and Gabriel Bonfim, were pulled by injury.
