Perth: Roger Federer makes his long-awaited return to tennis after six months out with a knee injury in tomorrow's mixed teams Hopman Cup in Perth ahead of next month's Australian Open.
The Swiss 17-time Grand Slam champion has not played a match since July when he tumbled during the final set of a loss to Milos Raonic in the semi-finals at Wimbledon.
Federer, 35, had surgery for the first time in his career on his left knee in February and after the Wimbledon set-back he did not finish the season, missing out on the US Open and Rio Olympics.
During his time out of the game Andy Murray and Novak Djokovic fought out the world No.1 ranking and his Swiss compatriot Stan Wawrinka won the US Open.
Federer makes his return with his world ranking down to 16, his lowest since 2001.
The Swiss legend, who will partner with Belinda Bencic, said he was looking to ease his way back before the start of the Australian Open in Melbourne on January 16.
"I'm really positive about how I'm feeling right now, and practice is going well," said Federer, who was watched by 5,000 fans at a practice session in Perth on Thursday.
"Expectations are low because I don't have the matches yet and it's going to be best-of-five from the get-go at the Australian Open.
"I'm happy I've got the Hopman Cup and I've got my three matches there to ease my way in."
Nick Kyrgios also makes his return in the Hopman Cup, but from a playing ban, after his spectacular meltdown at the Shanghai Masters in October resulted in an initial eight-week suspension.
A condition of the ATP reducing the ban to three weeks meant the controversial 21-year-old had to consult a sports psychologist to prepare him for the new season.
Kyrgios, who will partner with Daria Gavrilova in the Australian team, said he was now focusing on better managing his schedule and time.
Dual Wimbledon champion Petra Kvitova had pulled out of the Hopman Cup before she was knifed by a home intruder this month and required surgery on her racquet hand.
Kvitova will be out for six months and has been replaced in Perth by three-time doubles Grand Slam champion Lucie Hradecka, who partners with Adam Pavlasek in the Czech team.
