TEAM GB's reigning modern pentathlon Olympic champion Kate French has been forced to pull out of the event at the last moment.
The 33-year-old is the reigning Olympic champ and was hoping to defend the crown she won in Tokyo but she dropped out minutes before the 10am start time due to illness.
French was ranked fifth after Saturday's semi-finals, and would have been among the favourites for a medal on the final day of Paris 2024.
Team-mate Kerenza Bryson, who set an Olympic record in winning her semi-final, remains a contender for the gold medal on Sunday.
The 25-year-old, who is a qualified doctor and army reservist, is the reigning European champion and world bronze medallist.
Team GB sources have told SunSport that French is “devastated” at having to withdraw as she was desperate to try to retain her crown.

She had a horrible night and woke up feeling even worse and unable to give the performance she knew was required to get on the podium.
French has been replaced in the final by reserve athlete Annika Zillekens of Germany.
The BBC's Rishi Persad said: "Needless to say Kate is absolutely distraught and gutted.
"They said that's purely an illness. It's not Covid. Definitely not Covid. She tried to leave it as late as possible to continue.
