Novak Djokovic will decide over the next couple of days whether he will pull out of the Japan Open. The World No1 returned to training following a shoulder injury earlier this week.
Djokovic feels he may need more time to recover before he starts the defence of his Shanghai Masters title in a fortnight.
"I have been training without pain for two days and that makes me optimistic about the idea of fulfilling my calendar,” Djokovic said. “Between today and tomorrow, I will decide if I play Tokyo, but I feel safe in Shanghai.”
