Gael Monfils has withdrawn from the French Open which gets under way in Paris on Sunday.
The 29-year-old Frenchman has been advised by his doctor to pull out of the second grand slam of the year after being diagnosed with a viral infection.
The world No 14, who has also been suffering from a hamstring injury, has been in good form on clay this season having reached the final of the Monte Carlo Masters where he lost out to Spain's Rafa Nadal.
Monfils' best performance at Roland Garros came eight years ago when he reached the semi-finals.
His withdrawal comes less than 24 hours after world No 3 and 2009 champion Roger Federer pulled out through injury.
