Roger Federer has confirmed he has scheduled a tournament in 2022 as he continues his comeback from injury.
Federer has not played since Wimbledon last year, and that was only his fifth tournament in 18 months at the time.
He has been confirmed for the ATP 500 Swiss Indoors in Basel in October, suggesting he is still not entertaining any plans of retirement.
Federer, 40, has struggled with knee surgery since the 2020 Australian Open.
He underwent initial surgery a month after the tournament but required a further operation later in the year due to complications.
That appeared to be successful, and he made his comeback in Doha in March 2021. He followed that with a mini clay season, playing Geneva and the French Open before moving onto his favoured grass.
A disappointing performance at Halle was next before he reached the quarter-finals of Wimbledon, losing to Hubert Hurkacz.
Following that defeat, though, Federer revealed he required a third operation on his knee.
Basel is still some time away, though, and it would remain a major surprise if Federer does not compete at Wimbledon again this year - probably after a warm-up event or two.
He is also expected to play the Laver Cup at the O2 in September.
