Defending champion Novak Djokovic has pulled out of the ATP Finals because of an “ongoing injury”.
The 37-year-old Serb, who has won a record seven titles at the event, had already qualified as the sixth most successful player on the ATP Tour this season.
“I was really looking forward to being there, but due to ongoing injury I won’t be playing next week,” Djokovic wrote on social media.
Novak Djokovic, with 24 Grand Slam titles, won’t play again this season due to an unspecified injury after winning Olympic gold.
It is the first season since 2005 in which he has not won an ATP event and only the fourth since 2008 where he has not won one of the four Grand Slam titles.
