Novak Djokovic has pulled out of Serbia's opening Davis Cup semi-final match against the Czech Republic because of gastro-enteritis, an ITF spokeswoman said on Friday.
‘He does not play the first match. He is sick. He has gastro-enteritis,’ Barbara Travers told Reuters in Lyon, where France play Argentina in the other world group semi-final tie.
World number two Djokovic, who was due to play Radek Stepanek, will be replaced by Viktor Troicki.
Djokovic said on Thursday he was ‘exhausted’ after travelling back from the US Open, where he lost to Spain's Rafael Nadal in the final.
In Friday's second match, Janko Tipsarevic will face Tomas Berdych.
