Novak Djokovic was worried about his surgically repaired right knee at the Paris Games after feeling pain during a 6-3, 7-6 (3) victory over Stefanos Tsitsipas that put the 24-time Grand Slam champion in the Olympics semifinals for the fourth time as he pursues his first gold medal.
“I’m concerned about the state of the knee. I cannot give you exact information, because I don’t have it. I have to go and examine the knee now with my physio and with the medical staff of the tournament. And then let’s see,” said Djokovic, a 37-year-old from Serbia who will face Lorenzo Musetti of Italy on Friday.
