Two-time French Open runner-up Robin Soderling will miss the upcoming French Open while he recovers from mononucleosis.
The former world No. 4, sidelined since July of last year, will also miss this year's Wimbledon and Olympic events.
"I really want to come back. I haven't turned 28 yet and hopefully I have many years left," Soderling said. "Hopefully, I'll get back into shape fairly quickly."
Soderling reached back-to-back French Open finals in 2009 and 2010. He shocked a reigning four-time champion Rafael Nadal in the fourth round at Roland Garros in '09.
The big Swede is not sure when he will return to the ATP World Tour.
"I feel all right as long as I don't put too much stress on my body with heavy training," he said. "But I learned early on to not go back too quickly and I don't want another big setback."
The 27-year-old Soderling captured four titles on tour last year.
The 2012 French Open will commence Sunday in Paris.
