The former world men's tennis number one Rafael Nadal will make his comeback from injury at next month's Brazil Open.
The seven-time French Open champion has been suffering from tendonitis in his knee since Wimbledon last June.
Nadal was forced to withdraw from the Australian Open after his recovery was hit by a stomach virus.
The Spaniard has slipped to four in the world rankings during his absence from the Tour.
Nadal's appearance in the indoor tournament in Sao Paulo will be his first on the tour in South America since 2005.
The tournament begins on February 11th.
