The Ultimate Fighting Championship on Saturday will return to the UFC Apex for the first time in more than a month, and UFC on ESPN 34 comes with the expected step down in star power for what should still be a worthwhile exercise. In terms of relevance, this one is all about the headliner: a rematch that sees Vicente Luque and Belal Muhammad run back their 2016 encounter, this time with potential welterweight title implications attached. Beyond that, the highlights of the main card can also be found at 170 pounds, as Miguel Baeza faces Andre Fialho and Mounir Lazzez takes on Ange Loose in bouts that should guarantee action.
