Israel Adesanya will attempt to break into the record books in a light heavyweight title fight against Jan Blachowicz to close out UFC 259 on Saturday from the UFC's Apex Facility in Las Vegas.
Adesanya is already the middleweight champion, so his foray into the light heavyweight division gives him the opportunity to join an elite club of fighters who have simultaneously held two different championships in the organization.
Among those fighters is Amanda Nunes, who will be defending her featherweight title in the co-main event against Megan Anderson. The two-division champion has established herself as the best fighter in women's MMA.
