Kayla Harrison emerged as the leading contender for the UFC women's bantamweight title following her victory over Ketlen Vieira at UFC 307, despite facing severe health issues such as 'peeing blood' due to a grueling weight cut. Harrison's win, characterized by her wrestling and judo skills, positions her for a title shot against newly crowned champion Julianna Pena, who controversially won against Raquel Pennington in a split decision that many media members disagreed with. Post-fight, Harrison expressed disappointment over the decision and also criticized Pena for not acknowledging her as a future opponent, opting instead to call out Amanda Nunes. Former UFC champion Daniel Cormier also noted Pena's failure to mention Harrison in her post-fight interview. Harrison's transition from PFL to UFC has been challenging due to the weight class adjustment but has proven successful with two significant victories. Her pursuit of a UFC title could make her the first fighter to hold titles in both the UFC and PFL.
