UFC 266 looks a little different midway through fight week.

On Wednesday, the promotion announced that Karl Roberson has been removed from his middleweight bout due to illness. In his place, Dana White’s Contender Series alum Cody Brundage steps in to meet Nick Maximov.

The women’s flyweight bout between Manon Fiorot and Mayra Bueno Silva was scrapped from UFC 266 due to COVID-19 protocols. As MMA Junkie previously reported, Fiorot (who is asymptomatic) and her team tested positive for the virus.

The UFC also confirmed that the rematch between Nick Diaz and Robbie Lawler will be contested at middleweight instead of welterweight as originally agreed upon after Diaz asked for the change. Earlier Wednesday, Lawler indicated he had agreed to the last-minute change.

With the changes, here’s the updated UFC 266 lineup:
