The number of fans allowed to attend each day of the French Open has been cut to 5,000 because of surging coronavirus figures in the country.
Last week, the French Tennis Federation (FFT) said it planned to allow 11,500.
"The evolving hygiene situation in the Paris area has prompted the Paris police department to limit the number of spectators who may enter Roland Garros," said the FFT on Thursday.
The Grand Slam is set to start on 27 September at Roland Garros in Paris.
France recorded 10,593 cases on Thursday - the highest daily number since the pandemic began.
