The Ultimate Fighting Championship on Saturday will head back to the UFC Apex with a surprisingly solid show in Las Vegas. UFC on ESPN 36 figures to be a big night for the light heavyweight division in the main and co-main events, led by former champion Jan Blachowicz looking to rebound from a changing-of-the-guard loss by turning back surging contender Aleksandar Rakic. In the co-headliner, Ryan Spann and Ion Cutelaba should combine for an entertaining mess of a matchup that will likely serve as an important step forward for the winner.
