Multiple people with knowledge of the situation confirmed the news to MMA Fighting on Saturday afternoon. UFC officials later confirmed Ribas’ removal.
Ribas was set to face Angela Hill in a strawweight bout on the event’s main card at UFC APEX in Las Vegas. Ribas and her father, Marcelo Ribas, were not suffering any symptoms of the virus, sources told MMA Fighting.
Hill was two months removed from a decision win over Ashley Yoder, her second defeat of the octagon vet. The victory snapped a two-fight skid.
UFC Vegas 26 is headlined by a flyweight bout between Rodriguez and Michelle Waterson. The card lost two bouts on Friday due to weight-cutting complications and illness respectively.
