UFC light heavyweight champion Jon Jones is having his doubts that new undisputed UFC middleweight champion Israel Adesanya is serious about moving up to fight him.
Though Jones and Adesanya have been talking up a potential matchup in recent months and UFC president Dana White has even discussed the possibility of booking the two for a fight, Adesanya’s win over Robert Whittaker on Saturday at UFC 243 apparently did little to convince Jones that “The Last Stylebender” is truly ready for the challenge.
