Medvedev, 26, underwent minor back surgery early last month. He then thought it would take one to two months to recover. In Geneva, he will therefore make his comeback from May 15, where he hopes to gain the necessary competition rhythm for Roland Garros, which follows immediately afterwards.
Medvedev will not be allowed to participate in Wimbledon later this year. Wimbledon took the decision itself to ban Russian and Belarusian tennis players because of the war in Ukraine.
Medvedev was the losing finalist at the Australian Open at the beginning of this year. In February he briefly took over the first place in the ATP ranking from the Serb Novak Djokovic, but after his elimination in the third round at the Masters 1,000 tournament in Indian Wells, Djokovic again became number one.
