The UFC returned to Louisville, Ky., for the first time since 2011 Saturday with UFC on ESPN 57 at the KFC Yum! Center, and though the card started slow, it picked up late. Although controversial, Nassourdine Imavov (14-4 MMA, 6-2 UFC) picked up the last of six stoppage results when he earned a fourth-round TKO of Jared Cannonier (17-7 MMA, 10-7 UFC) in the middleweight headliner.
