Johnny Walker, who recently moved up to heavyweight in the UFC, has gone 2-0 at the new weight class after stopping Waldo Cortes-Acosta in round three on Saturday. Walker has expressed openness to a stunning seven-day turnaround to serve as a back-up option for a title fight at UFC 334. His quick availability makes him a potential emergency replacement should the scheduled contender be unable to compete.
