Novak Djokovic looks set to miss another event in the US ahead of the US Open, albeit being an exhibition event. The US Open announced that the likes of Rafael Nadal, Iga Swiatek, Coco Gauff, and Carlos Alcaraz, among others, will play an exhibition event in the week before the Grand Slam tournament, with the proceeds of the event going towards the war-affected people in Ukraine.Tennis fans expressed their thoughts on the charity event that will feature some of the biggest stars in the sport. While many were excited by the great line-up, Djokovic's fans once again urged the relevant authorities to let him into the country to play the US Open.The likes of Taylor Fritz, Felix Auger-Aliassime, John McEnroe, Leylah Fernandez, Jessica Pegula, and Victoria Azarenka will also be part of the charity event, where all players involved will play a series of singles and mixed doubles matches.As the event is being held with the sole purpose of helping those affected by the Russia-Ukraine war, a fan opined that Djokovic should be present for such an event, given the fact that he has himself been through a similar situation in the past."If anyone understands anything about the effects of war, its THIS guy Novak Djokovic!!! He is trying to bring PEACE to so many in the Balkans by uniting & spreading love without boundaries! It will be a travesty if he of all people is not at this event!" said a post on Twitter.Kristina@KrisSekMNT@usopen If anyone understands anything about the effects of war, its THIS guy @DjokerNole !!!He is trying to bring PEACE to so many in the Balkans by uniting & spreading love without boundaries!It will be a travesty if he of all people is not at this event!#LetNovakPlay @usta241@usopen If anyone understands anything about the effects of war, its THIS guy @DjokerNole !!!He is trying to bring PEACE to so many in the Balkans by uniting & spreading love without boundaries!It will be a travesty if he of all people is not at this event!#LetNovakPlay @usta https://t.co/87KTIa7VVCKiza@ZGocicYou are missing the very important one @DjokerNole . #letnovakplay twitter.com/usopen/status/…US Open Tennis@usopenStars of the game unite for the Tennis Plays for Peace Exhibition match.

View this post on Instagram Instagram PostThe Serb missed the ongoing Canadian Open as Canada is following the same vaccine rules that currently deny him entry into the US. He is currently ranked No. 6 in the ATP rankings and is likely to fall further if he eventually does not play in the US Open. He will miss the Cincinnati Open next week if he is not granted an exemption in time for the ATP Masters 1000 event.The Serb reached last year's final at the New York Grand Slam, where his bid for a Calendar Grand Slam was ended by Daniil Medvedev.
