Norrie was in Seoul, South Korea taking part in the Korea Open when he got a positive test. He withdrew prior to his quarter-final match against Jenson Brooksby. He announced today that he pulled out of the Tokyo Open as well due to the same reason being stuck in isolation in Seoul:
"Unfortunately I had a positive Covid test in Korea and wasn’t able to compete in the rest of my matches. I have no symptoms and I am feeling 100%. I was really hoping to go to Tokyo but because of the quarantine period I will not be able to play there.”
The good news for Norrie is that he is without any symptoms which should allow him to return to competition immediately after returning to Europe. Norrie is in the middle of the Race mostly due to not getting the points from this year's Wimbledon but that's something many other players are missing as well.
