Djokovic in Davis Cup action

Belgrade - New US Open champion Novak Djokovic will play the opening singles match for Serbia in the Davis Cup semifinals against David Nalbandian of Argentina after the draw was made known in the Serbian capital.

In Friday's other singles match, Janko Tipsarevic will face Juan Martin del Potro.

Djokovic, however, was not present for Thursday's draw at the Belgrade Arena. Davis Cup officials said Djokovic has been held up in New York and will join the team later.

Djokovic beat Rafael Nadal on Monday to win his third Grand Slam title this year. He also won Wimbledon and the Australian Open, but lost in the French Open semifinals.

In Saturday's doubles, Janko Tipsarevic and Nenad Zimonjic will take on Juan Monaco and Juan Ignacio Chela, with the reverse singles to take place on Sunday.

The Serbs are the defending champions after they defeated France in last year's final.
