Andy Schleck has delayed his return from the respiratory infection that forced him to abandon last week's Tour of the Mediterranean.
The 2010 Tour de France winner, who also struggled at the season-opening Santos Tour Down Under in January, said he would make his comeback at the two-day Tour du Haut Var-Matin in the south of France on Saturday and Sunday.
Although he is back to full health, the 27-year-old Luxembourg rider is not yet fit to race and will instead return to competition at the Grand Premio Città di Camaiore on February 28.
His RadioShack-Leopard team manager, Luca Guercilena, said: "We were happy to see Andy doing well in training the last few days. There is, however, a big difference between training and race situations.
"We want to prevent a relapse because of the race. Andy's main goals are situated later in the season. It is better that we are cautious now instead of taking steps backward."
Schleck will spend the next few days training in Mallorca.
