The Czechs chose Tomas Berdych and Radek Stepanek,who played all five matches when they beat Spain 3-2 in last years final in Prague. Lukas Rosol and Jan Hajek were also in the Czech squad for the November 15-17 final. The Czechs were in the final for the third time in five years. Serbia was back at the same court where it won its only cup in 2010. Tipsarevic is struggling with a leg injury.

We will know Jankos condition in two,three days,when he finishes treatment, Serbia coach Bogdan Obradovic said. Janko is doing all he can to recover and be ready for the duel. But,we wont do anything to jeopardise his career.

Troicki out

Serbia had hoped Viktor Troicki might be available,but his appeal against an 18-month ban for skipping a blood test in April was reduced to 12 months by the Court of Arbitration for Sport on Tuesday,meaning he cant play until July.

Troicki played in the first two wins this year over Belgium and the United States,and won the decisive point in the 2010 final against France.

Despite Troicki,Obradovic said he knows he can count on Djokovic,who hasnt lost a cup match since the 2011 semifinals.

Novak is a great professional,he is ready, Obradovic said. Davis Cup is one of his priorities,so I have no doubt that he will be ready for the Czechs.

En route to last years Davis Cup victory,the Czechs beat Serbia 4-1 in the quarterfinals in Prague.
