Novak Djokovic’s dream season could be at risk of ending on a low note after the world number one lost only his fourth match of 2011 when he went down 2-6, 7-6 (7/4), 6-0 on Saturday to Japan’s Kei Nishikori in the semi-finals of the Swiss Indoors. Djokovic said he had been playing all week with a sore shoulder similar to the injury which forced him to quit the Cincinnati final in August against Andy Murray before the US Open. “I could barely serve for much of the match, I was in pain,” said the Serb, who has won ten titles in 2011 but only returned this week after six weeks out with a back injury. “My shoulder is very bad, we won’t even talk about the third set. I have a lot of pain inmy body from the competition this week. I hope I can be ready for Paris.” That Masters event starts on Monday, with Djokovic now in serious doubt of fronting up. He said he is likely to travel to the city and hope for the best.
