(Reuters) - Rafa Nadal's withdrawal from the Monte Carlo Masters has cast doubt over the 22-times Grand Slam champion's participation at the French Open, but Novak Djokovic said he is still hoping for a final chapter in their storied rivalry.

The 37-year-old Spaniard, who has said he expected to retire after the 2024 season, returned to competition in Brisbane in January, after almost a year sidelined with a hip flexor injury, but has not played an ATP event since.
