World’s number one Novak Djokovic will have to undergo surgery because of the problems with shedding of the nails on the fingers of the right foot. This is the same problem he had on some of the previous tournaments, but now he will really have to address it.

Novak Djokovic has asked for a medical time-out during the final match of the U.S. Open against Stan Wawrinka. He didn’t look good on the field, and even if this was unpopular decision amongst the crowd and his opponent, it just had to be done.

He has endured criticism for the time-out, but now it’s clear that he had no other option, but to call it. He was getting medical attention for a few minutes, and it was evident he had problems with his feet. He looked pale on the field compared to his status as world’s number one and some of his performance on previous matches.

Wawrinka was a better player during the duel, and in the end aided by Novak’s injury he won his first title at the U.S Open.

After the tournament, it was diagnosed that Djokovic’s fingers were gripped by infection and that he will need to undergo the surgery to remove the remaining parts of the nails. This was confirmed by Novak’s coach Marian Vajda in an interview with Ubitennis.com.

Because of the surgery, it is not sure whether Djokovic will be able to play at a charity event in Milan on September 21 and 22. The friendly tournament called “Djokovic and friends” organized by Djokovic should feature Serena Williams, Rafael Nadal, Fabio Fognini and Flavia Pennetta.

According to sources, Novak Djokovic should recover by the tournament in Beijing that is scheduled to start on October 3.
