Earlier on Tuesday, world number one Jannik Sinner withdrew from the Masters 1,000 due to illness.
Italian Sinner said he contracted a virus after arriving in the city early to train for the event.
“Today I already feel a little better, but my body is not ready to compete and I still feel very, very weak,” said the 23-year-old.
“It makes no sense to go out on the field and try to compete.”
Sinner hopes to recover before the ATP Finals, which will take place in Turin from November 13-20.
