David Nalbandian will miss the French Open after an illness hampered his recovery from a hernia operation and a muscle injury.
Nalbandian lost weight after his injury in March and his comeback had been hit by a fever that interrupted his training.
His spokesman, Bernardo Ballero, told The Associated Press on Tuesday that the Argentine is "not right physically."
Nalbandian, No. 24 in the rankings, made the semifinals at Roland Garros twice, in 2004 and 2006.
Ballero says the former third-ranked player hopes to be back for Queens, a warm-up tournament for Wimbledon. Nalbandian was runner-up to Lleyton Hewitt at Wimbledon in 2002.
