Roger Federer has withdrawn from the ATP Cup, a new team competition to be held in Australia in January, citing "family reasons". "It is with great regret that I am withdrawing from the inaugural ATP Cup event," Federer said in a statement. "When I entered the event last month, it was a really difficult decision because it meant less time at home with the family and a fully intense start to the season.
"After much discussion with both my family and my team about the year ahead, I have decided that the extra two weeks at home will be beneficial for both my family and my tennis."
The ATP Cup organisers tweeted: "@rogerfederer announced that he would not play the #ATPCup for family reasons and therefore Switzerland was removed" from the competition.
The ATP Cup is a new competition which competes with the revamped Davis Cup and will be held in Brisbane, Perth and Sydney from January 3-12.
"It pains me to not be a part of the most exciting new event on the calendar," Federer said.
"But this is the right thing to do if I want to continue to play for a longer period of time on the ATP Tour."
"For my Australian fans, I look forward to seeing you all at the Australian Open, fresh and ready to go."
The Davis Cup will be held November 18-24 in Madrid but Switzerland did not qualify.
Federer will next play at the ATP Tour Finals in London, which get underway on November 10.
