LONDON, June 27 (Reuters) - British number one Johanna Konta has been forced to withdraw from Wimbledon after a member of her team tested positive for COVID-19, the All England Club said on Sunday. Konta, who was seeded 27th, must undertake a 10-day quarantine period after being identified as a close contact. "A member of Johanna Konta"s team presented with COVID-19 symptoms this morning, and immediately isolated and undertook a PCR test in accordance with The Championships" testing protocols," a statement said. "A positive result was returned which resulted in the AELTC, together with Public Health England, identifying Johanna Konta to be a close contact. In line with government legislation, she is required to self-isolate for 10 days and therefore is withdrawn from The Championships."
