A statement from Strictly Come Dancing said: “We can confirm Motsi Mabuse will not be taking part in Strictly Come Dancing this weekend.
“We are delighted that Cynthia Erivo will be joining us as a guest judge again, joining Craig Revel Horwood, Anton Du Beke and head judge Shirley Ballas on the judging panel.
“We look forward to having Motsi back with us next weekend.”
Erivo, who was nominated for a Best Actress Oscar last year for her role in the film Harriet, joined the judging panel last weekend for Musicals Week while Revel Horwood was in isolation. She impressed when she gave Rose Ayling-Ellis, the show’s first deaf contestant, feedback for her dance routine through sign language.
The absence of the two judges is the latest setback to hit Strictly this season. Judi Love, Tom Fletcher and Amy Dowden, his dance partner, all tested positive for coronavirus over the course of the series, while Robert Webb and Dianne Buswell, his dance partner, withdrew from the show over the TV star’s ill health.
Ugo Monye, the former England rugby international, was also sidelined due to a back injury.
