Only 5,000 fans per day will be allowed in at the French Open amid a spike in coronavirus cases in the country.

Main-draw matches are scheduled to begin at Roland Garros on September 27 after the grand slam was moved due to COVID-19.

It was announced earlier this month that 11,500 spectators would be allowed in per day, although several players raised concerns after the US Open was held behind closed doors.

France reported 10,593 new cases of coronavirus on Thursday before a reduced capacity for Roland Garros was announced.

"The FFT [French Tennis Federation] will therefore assume the responsibility of organising the tournament with a new lay out," a statement read.

"It is important for the sporting, social and economic life of the country that a major event like Roland Garros can be put on while respecting health imperatives.

"Such will be the case for the 2020 tournament.

"The FFT is conscious of how disappointing this news will be for those who will not be able to come to the stadium due to the reduction in capacity. We would like to thank you for your understanding and your dogged support of the tournament.

"Roland Garros 2020 will set an example by endorsing, promoting and defending its cherished sporting values."
