Gautier enters UFC 320 riding the momentum of a first-round knockout over Robert Valentin at UFC 318 in July, marking his seventh consecutive knockout victory. He earned his UFC contract in September 2024 with a second-round stoppage of Yura Naito on Dana White's Contender Series.
“The Silent Assassin” now boasts a professional record of 8-1, including an unbeaten 2-0 slate in the UFC.
Meanwhile, Vines most recently competed at AFC 12: The Great Commission in August, scoring a first-round knockout victory. The 29-year-old American was set to face Andreas Tricomitis at LFA 219 next weekend before earning the call-up to the UFC.
Until now, Vines has primarily competed in regional promotions, amassing a professional record of 10-3, with seven of those wins coming by stoppage.
