Paris: Novak Djokovic pulled out of the Paris Masters with a nagging shoulder injury before his quarterfinal against Jo-Wilfried Tsonga on Friday.
The top-ranked Djokovic announced on his website that the injury got worse after his third-round comeback win against fellow Serb Viktor Troicki on Thursday.
"Sadly I have to inform you that I have withdrawn from the tournament. I have pushed myself to the limit by playing, and after the match yesterday my shoulder got worse," Djokovic wrote. "For this reason, I have to put my health first and withdraw even though my urges as a professional player are making me want to play until the last drop of energy."
