Dominic Thiem has had to withdraw from the Monte-Carlo Masters having only just recovered from Covid-19 picked up in Marbella last week.
The 28-year-old announced on social media that he has tested negative on Thursday morning, but it means the 2020 US Open champion has not recovered quickly enough to take part in the Masters tournament which gets underway on Monday. Thiem has been replaced in the main draw by Italy's Lorenzo Musetti.
