Rafael Nadal has withdrawn from the inaugural International Premier Tennis League that begins in late November.
The Spaniard said he needs to use this period in the off season to prepare for the 2015 ATP Tour season instead.
Organisers were quick to replace one tennis superstar with another however as Roger Federer agreed to step up and replace his rival.
Founder of IPTL, Mahesh Bhupathi said: “In the format we have, there is something, you know, neither party wanted to kind of take a chance with. When you are talking of profile as high as Rafael Nadal, there was probably only one name that could have helped ease the pain and for us fortunately Roger was available and we made it happen.”
Federer has been named in the Indian Aces – one of four teams of seven players competing.
His teammates are Ana Ivanovic, Sania Mirza, Gael Monfils and seven-time Wimbledon champion Pete Sampras.
Andy Murray, Novak Djokovic, Serena Williams, Maria Sharapova, Pat Rafter and Andre Agassi will also play at the inaugural event.
The tournament begins on November 28, will be played in Manila, Singapore, Delhi and Dubai, with the final on 13 December.
