Tokyo Olympics: Novak Djokovic "Not Sure" About US Open Fitness After Olympics Nightmare

Tokyo Olympics: World No.1 Novak Djokovic said he was "not sure" about his fitness for US Open after he pulled out of Olympics mixed doubles bronze-medal match with a shoulder injury.

World number one Novak Djokovic said he was "not sure" about his fitness for the US Open after pulling out of the Tokyo Olympics mixed doubles bronze medal match with a shoulder injury on Saturday. The 34-year-old Serb could become the first man to complete a calendar Grand Slam since Rod Laver in 1969 when the US Open gets under way on August 30. The withdrawal in Tokyo came after the 20-time major champion lost his cool on his way to a surprise 6-4, 6-7 (6/8), 6-3 defeat against Pablo Carreno Busta in the Olympics singles bronze-medal match. He admitted that his exertions in Japan have taken their toll but he still hopes to be fit enough to challenge at Flushing Meadows. "The consequences physically hopefully will not create a problem for me for the US Open, but that's something that I'm not sure about right now," said Djokovic. "But I'm not regretting for giving it all because at the end of the day, when you play for your country, that's necessary."
