Alex Pereira took out another dangerous contender at UFC 307, but his toughest test as light heavyweight champion is probably still to come.
Pereira was back in action in the main event of the Saturday card in Salt Lake City, taking on fellow knockout artist Khalil Rountree. While it was a great fight on paper, the booking was the subject of some controversy, as many believed the title shot should have gone to No. 2-ranked Russian wrestler Magomed Ankalaev rather than Rountree. After Pereira stopped Rountree with a barrage of uppercuts in round four, the Ankalaev fight is probably next, and if it happens, it's arguably the toughest stylistic matchup of the Brazilian MMA career to date.
