World's No 1 Rafael Nadal and US Open champion Juan Martin del Potro say they will play in the Thailand Open in September.
Nadal, the reigning Wimbledon and French Open champion, withdrew from last year's Thailand Open due to a knee injury.
In a statement issued Thursday, the Spaniard said "this year with my health and body in good shape, I am really looking forward to playing some great tennis for the Thai fans."
Del Potro, currently ranked No 7, has not played in a tournament since the Australian Open in January due to a right wrist injury.
The Thailand Open is held in Bangkok from Sept 24 to Oct 3.
