The Swiss star hasn’t been seen since a shock Miami Open first round exit to Thanasi Kokkinakis in March.
Federer has since taken the rest of the spring off to rest ahead of a busy summer schedule, where he will aim to retain his Wimbledon title.
But tennis’ other big names are all battling it out at the French Open this week in an attempt to win the pinnacle of the clay-court events.
And according to a survey of audience members at Roland Garros, Federer’s absence isn’t affecting morale in Paris.
“We’ll see his heirs [Grigor] Dimitrov and [Dominic] Thiem anyway,” said one fan.
“And then Nadal – Because even if you’re fans of Federer, it’s a healthy rivalry.
“I enjoy seeing ‘old people’ again teaching young people.
“About twenty years ago, [Ivan] Lendl, at the same age, had already retired.”
While one tennis spectator said: “He increases his chances for the rest of the season by not coming here: he has an interest in winning Wimbledon!
“Next year too, it’s unlikely he’ll come.
“And if he comes back as part of a farewell tour, it will not be a good sign, because that means he will end his career.”
L’Equipe did manage to spot one fan with a Roger Federer cap in the audience.
However, even that supporter admitted she wasn’t upset about the 36-year-old’s absence.
“It’s my brother who gave me the cap,” said the Roland Garros audience member.
“I come here for the atmosphere and the french players.
“To tell the truth, it does not change much for me that he is not there.”
