French Open fans must show they are free from Covid-19 if they want to be among the small number of spectators allowed to attend this year's Roland Garros, organisers said Wednesday. French tennis federation director-general Amelie Oudea-Castera said potential spectators at the May 30-June 13 Grand Slam must demonstrate proof that they had a negative PCR or antigen test within 48 hours of attendance, or bear a certificate of vaccination. es-ig/lp/mw
