The former world number one Ivan Lendl will end a 16-year exile from tennis by joining the ATP Champions Tour.
The eight-times Grand Slam winner from the Czech Republic will make his Tour debut at the Jean Luc Lagardere Trophy in Paris in October, the scene of his three French Open victories.
The 50-year-old will come face-to-face with the man he defeated to win his first Grand Slam title in the same city in 1984 - John McEnroe.
Since retiring in 1994, Lendl has barely lifted a tennis racquet, preferring to spend his time on the golf course and with his wife and five children.
Also set to compete in the French event is France's Yannick Noah and Swede Mats Wilander, both former French Open champions.
The six-man field will be rounded off by two players to be announced in the coming weeks.
