Third seed Elena Rybakina became the latest high-profile withdrawal from the Olympic tennis competition on Thursday, hours after the draw was made at Roland-Garros.
Kazakhstan's former Wimbledon champion pulled out of the singles and mixed doubles, in which she was to partner with Alexander Bublik.
No reason was given for her decision.
France's Caroline Garcia will now move into Rybakina's spot in the draw as the 17th seed and open with Romania's Jaqueline Cristian, while Australia's Daria Saville enters the draw as an alternate.
