Coria positive, Nadals returns a negative test
After returning home from the Mubadala World Tennis Champioships 10 days ago, Nadal announced: "On my return home after playing the Abu Dhabi tournament, I have tested positive for Covid in the PCR test that was performed on me when I arrived in Spain.
"Both in Kuwait and Abu Dhabi we passed controls every two days and all were negative, the last being on Friday and having the results on Saturday. "I am having some unpleasant moments but I hope that I will improve little by little.
I am now homebound and have reported the result to those who have been in contact with me. "As a consequence of the situation, I have to have total flexibility with my calendar and I will analyse my options depending on my evolution.
"I will keep you informed of any decisions about my future tournaments! Thank you all in advance for your support and understanding." Luckily, Nadal has since returned a couple of negative tests and he has returned to the practice court.
