The octagon traveled to Saudi Arabia for the first time Saturday with UFC on ABC 6 at Kingdom Arena in Riyadh, and in the main event, a former champion delivered one of his career-best wins. Ex-middleweight titleholder Robert Whittaker (26-7 MMA, 17-5 UFC) showed up in a big way with a first-round knockout of short-notice replacement opponent Ikram Aliskerov (15-2 MMA, 2-1 UFC), proving he’s still among the top of the heap in the weight class. It was one of just four stoppages on the 11-bout card, and for more on the numbers, check below for MMA Junkie’s post-event facts from UFC on ABC 6. * * * *
