Medvedev, who won the US Open last year and lost in the Australian Open final to Rafa Nadal in January, will likely miss out on this month’s Monte Carlo Masters as well as the ATP 1000 events in Madrid and Rome in May.
“The last months I have been playing with a small hernia. Together with my team I have decided to have a small procedure done to fix the problem,” world No 2 Medvedev wrote on Twitter.
“I will likely be out for the next 1 – 2 months and will work hard to be back on court soon. Thanks for all the support.”
Medvedev’s bid to reclaim the world No 1 ranking fell short on Thursday as the Russian lost 7-6(7), 6-3 to Poland’s Hubert Hurkacz in the Miami Open quarterfinals.
The French Open will be held in Paris from May 22 to June 5.
