Reigning Australian Open men’s singles champion Novak Djokovic was expected to be in action in his men’s quarter-final against Norwegian seventh seed Casper Ruud.
However, 24-time Grand Slam winner Djokovic, 37, had to withdraw after a scan revealed he had suffered a torn medial meniscus in his right knee.
Ruud gets a walkover win into the semi-finals and will play the winner of the one men’s quarter-final tie to be played on Wednesday.
Each evening session of the French Open has seen a men’s match and that run will continue as German fourth seed Alexander Zverev takes on Australia’s Alex de Minaur, the 11th seed.
It could be another late finish for Zverev after a thrilling five-set win over Holger Rune in the last round ended at 1:40am local time.
Zverev, 27, is playing in Paris under the shadow of an ongoing trial in Berlin relating to allegations he assaulted an ex-girlfriend, which he denies.
The German is still hunting his first Grand Slam title and has fallen at the semi-final stage of the past three French Opens.
De Minaur defeated fourth seed Daniil Medvedev in round four to become the first Australian to reach the quarter-finals in Paris since Lleyton Hewitt in 2004.
For De Minaur, the boyfriend of Britain’s Katie Boulter, this will be his second Slam quarter-final having lost in three sets to eventual winner Dominic Thiem at the 2020 US Open.
