World number one Jannik Sinner has withdrawn from the Rolex Paris Masters due to a virus.
Sinner, who won the Australian Open and US Open titles this season, has been replaced in the draw by France’s Arthur Cazaux.
The 23-year-old Italian said: “It’s a very tough announcement. I’m not going to play here in Paris.
“We came here very early to prepare in the best possible way. After the first practice session I really didn’t felt good. Today I feel better already a little bit, but the body is not ready to compete and I still feel very, very weak.
“It doesn’t make sense to go on court and try to compete for this tournament.”
Sinner has already secured the end-of-year number one ranking and hopes to be fit for the ATP Finals in Turin from November 10-17.
“The most important part is to recover and get back physically 100 per cent,” Sinner added.
