LAS VEGAS – Just one fight into his UFC career, Vinicius Oliveira shot a reasonably big shot Saturday in Las Vegas. Oliveira (20-3 MMA, 1-0 UFC) outworked Ricky Simon (20-5 MMA, 8-4 UFC) for a unanimous decision to open up UFC 303 at T-Mobile Arena, the anchor of International Fight Week. Then he called out unbeaten bantamweight standout Umar Nurmagomedov , cousin of former UFC champ Khabib. “I’d like to fight so much against Umar Nurmagomedov,” Oliveira said at his UFC 303 post-fight news conference.
