Belgrade, Serbia – Fresh off his nearly-six-hour victory over round tie against visiting Sweden.
Djokovic needed 5 hours, 53 minutes to stave off Nadal in five sets in Melbourne and is looking forward to some much-needed rest.
Serbian captain Bogdan Obradovic made the decision to rest Djokovic.
The Serbs should be in good hands with world No. 9 Janko Tipsarevic and 22nd- ranked Viktor Troicki.
The 2010 champion Serbs will host the Swedes in Nis from February 10-12. Serbia whipped a host Sweden 4-1 in the quarterfinals last year.
Djokovic led Serbia to its first-ever Davis Cup title two years ago.
