The UFC 320 card has been dealt its first disruption.
UFC 320 is set for this Saturday, October 4, at the T-Mobile Arena in Las Vegas, Nevada. The pay-per-view event will be highlighted by a championship doubleheader, with UFC light heavyweight champion Magomed Ankalaev defending his title in a highly anticipated rematch against former champion Alex Pereira in the main event.
Meanwhile, in the co-main event, reigning UFC bantamweight king Merab Dvalishvili will aim for his third title defense of the year against perennial contender Cory Sandhagen.
However, just five days out from the event, the stacked UFC 320 card has already taken a hit, as
on Monday via social media that he is withdrawing from his middleweight bout against Ateba Gautier due to medical issues.As of now, it remains unclear whether Gautier will take on a replacement opponent on such late notice, or if the bout has been completely canceled or postponed to a later date.

On the other hand, Gautier is coming off a first-round knockout win over Robert Valentin at UFC 318 in July, extending his undefeated knockout streak to seven fights. “The Silent Assassin" holds a professional record of 8-1, including 2-0 in the UFC.
