Last Thursday, Federer won back-to-back matches against Joao Sousa and Borna Coric at the Italian Open to reach the quarter-finals.
But on Friday, just hours before he was due to face Stefanos Tsitsipas, it was announced Federer had withdrawn from the tournament due to a right leg injury.
Federer had revealed prior to the match that he had hurt his toe and leg slipping on the wet baseline against Coric.
The Swiss dispelled concerns about potentially missing the French Open when he practised on the newly renovated Court Philippe Chatrier for the first time in four years on Tuesday.
That evening, Federer was among a star-studded line up including actors Natalie Portman and Uma Thurman at a Moet & Chandon event at Chateau de Saran.
The 37-year-old was asked about his leg and he replied: “I’m fully recovered.”
And the 2009 French Open champion said he was delighted to be returning to Paris for the clay court Grand Slam.
“I’m incredibly happy to be returning to Roland-Garros; I haven’t played the French Open in three years,” he said.
“The audience’s expectations are high, but I’m trying to calm things down because I feel it’s going to be hard.
“But things went well for me in Rome and Madrid so I am really very satisfied.”
This year’s French Open marks ten years since Federer won his one and only title in Paris.
And tennis pundit Mark Petchey feels Federer is in a four-man group behind Rafael Nadal to win the Coupe des Mousquetaires trophy.
“I still have Rafa as favourite,” Petchey told ITV Sport.
“The size of the court along with his reputation there are huge advantages.
“Sense though that certain players feel they can beat him which changes the dynamic heading in.
“Thiem, Djokovic and Fognini have great shots this year along with Federer.”
