He starred in a pair of title fights, with featherweight champion Alexander Volkanovski defending his belt in the main event against “The Korean Zombie” Chan Sung Jung. At BetMGM, Volkanovski is a huge favorite -750 over Jung which is +500. In the co-main event, tough opponents will meet for the second time, as bantamweight champion Aljamain Sterling (+360) defends interim champion Petr Yan (-500). The most attention-grabbing match is the last one without a title on paper, the welterweight bout between No. 2 Gilbert Burns (+375) and 11th-ranked Khamzat Chimaev (-550). Chimaev has gone 4-0 with four finals in the UFC and his games are over immediately. In Burns, however, he faces a three-time world jiu-jitsu champion and a former welterweight title contender.
