Sir Bruce Forsyth will be unable to host Saturday night's Strictly Come Dancing after falling ill with the flu.
The veteran presenter, 85, has hosted the hit show since it launched in 2004.
He last missed a programme because of illness in 2009.
Claudia Winkleman is stepping in as a replacement for Sir Bruce, fronting Strictly alongside Tess Daly.
The BBC said, "Sir Bruce Forsyth has the flu and therefore isn't feeling well enough to present tomorrow's Strictly Come Dancing on BBC One.
"The show looks forward to his return this week."
Saturday will see the Strictly stars take to the dance floor and face the public vote for the first time.
Abbey Clancy and her professional partner Alijaz Skorjanec topped the leader board last week, with a total of 32 points from the judges.
The points accrued by each couple last week will be carried over to the weekend, when one couple will leave the series.
