Novak Djokovic says there is “nothing damaged” in his left arm despite taking a nasty fall during his third-round match at Wimbledon against Gilles Simon.

Djokovic crumpled to the ground after reaching for a forehand in the sixth game of the third set and immediately grabbed his left shoulder.

The top-seeded Serbian walked gingerly to his chair, while still holding his left shoulder, before taking a medical timeout. Djokovic was able to finish the match with a 6-4, 6-2, 6-4 win over the Frenchman.

“I had an awkward fall so I was just hoping that there was nothing bad going on with the joint and luckily there isn’t,” Djokovic said.

He added that he felt “sharp pain” and the muscle “was quite sore because of the impact” but that “luckily there is nothing damaged.”

Djokovic next plays No. 14 seed Jo-Wilfried Tsonga of France.
