The Swiss ace has been sidelined since July with a knee problem that required surgery, with his last competitive appearance coming at Wimbledon, when he lost in the semi-finals at SW19 to Milos Raonic.
The 17-time major winner is now in line to make his competitive comeback in next month's IPTL, which has been reduced to four teams and three venues for 2016.
Federer is one of the headline names for the event alongside Serena Williams, Kei Nishikori and Tomas Berdych, with the likes of Andy Murray and Novak Djokovic not competing in the tournament.
The 35-year-old is scheduled to play in Hyderabad on December 9 and 10, with the Aces set to take on the Singapore Slammers and the UAE Royals, before the final of the competition will take place on December 11.
Federer won the inaugural IPTL tournament with the Aces in 2014 and he will be hoping to replicate that feat this year, as he bids to prove his fitness ahead of the 2017 season.
