The Badminton World Federation (BWF) confirmed that Indonesian shuttlers were withdrawn from the 2021 Yonex All England Open due to COVID-19 protocols.

A number of players and team members from the Indonesian team were contacted by the UK government’s National Health Service (NHS) Test and Trace service and are required to self-isolate with immediate effect.

In accordance with the UK government's requirements, the entire team would self-isolate for 10 days from the date of their inbound flight after a person travelling onboard tested positive for COVID-19.

"While we regret this unfortunate consequence, BWF and Badminton England will continue to follow all protocols required by the UK government and the local health authorities to ensure the safety of all participants.

"All results to date will stand and the draw will remain unchanged. All scheduled opponents in the next round will be given a walkover," read an official statement from the BWF.

Marcus Fernaldi Gideon-Kevin Sanjaya Sukamuljo and Mohammad Ahsan-Hendra Setiawan had already participated in the men's doubles first round, beating Matthew Clare-Ethan Van Leeuwen and Ben Lane-Sean Vendy respectively.

Indonesian men's singles player Jonatan Christie also overcame Kunlavut Vitidsarn in the first round.

Following the announcement, Gideon took to Instagram to voice his shock at the decision.

"The BWF has failed to organise this matter. Before the flight, all of the Indonesia team tested negative and we were also been re-tested by the time we reached the hotel," he wrote.

"Some of you may notice that the game today was delayed prior to seven positive cases they found in other team members [from another country]. After they were retested, the result were all turned negative. So why didn’t we also have the same justice?

"If there are strict rules for entering the British area due to COVID-19, the BWF should have enrolled a bubble system that guarantees our safety. Players should have undergone a quarantine before the event.

"To be fair, the person who has tested positive should have undergo another test because truly we have no faith anymore in their COVID-19 test; as you all can see, all the seven positive cases can turn into seven negative cases in just one day."
