Novak Djokovic and Matteo Berrettini were in quarter final action.
5,000 fans were booted out of the Philippe Chatrier Court last night before Novak Djokovic booked his French Open semi-final place.
The main court at Roland Garros had been one-third full for his quarter-final with Matteo Berrettini.
But the curfew in Paris meant those fans missed the conclusion, with Djokovic beating the Italian in four sets.
The top seed sets up a 58th career meeting with Rafa Nadal.
