BELGRADE, Serbia -- Novak Djokovic, who pulled out of the quarterfinals at the Dubai Championships last week with an inflammatory infection in both eyes, will play the opening match against Aleksandr Nedovyesov on Friday when Serbia takes on Kazakhstan in the first round of the Davis Cup.
Djokovic's participation is a boost for the host team.
"I have known Nedovyesov from his junior days," Djokovic said. "I have seen him play several times, but I am cautious because surprises are possible in such matches."
Djokovic led Serbia to its only Davis Cup title in 2010, but he's not looking past Kazakhstan.
"We must first overcome this obstacle," the top-ranked Serb said. "The most important thing is to be prepared, start the match with high intensity and use the audience support, which can be crucial."
Viktor Troicki will follow in the second singles match against Mikhail Kukushkin, while Djokovic and Nenad Zimonjic are slated to play in Saturday's doubles against Andrey Golubev and Nedovyesov.

* Andy Murray sees no reason why Britain can't retain the Davis Cup. After its first title in 79 years, the Brits will face Japan in a first-round tie beginning Friday.
Said Murray: "I never thought I would be able to do it, but then when we did, it was like, 'Why not, why can't we do it again?"
Murray will open the indoor hard-court matches against Taro Daniel, whom he has never met. The second singles features Kei Nishikori against Daniel Evans, who replaced Kyle Edmund, who injured his back in practice Wednesday.
The doubles on Saturday features Dominic Inglot and Jamie Murray against Yoshihito Nishioka and Yasutaka Uchiyama.

Gilles Simon will take on Vasek Pospisil in the second singles match, and Richard Gasquet and Jo-Wilfried Tsonga are set to take on Philip Bester and Pospisil in doubles.
