Grand Slam tennis is back: but not as we know it.
For the first time since the world was gripped by the coronavirus pandemic, one of the four major tournaments is taking place when the US Open starts in New York on Monday.
Several top names will not be playing at Flushing Meadows, although there is still plenty of star power in the form of Serena Williams, Novak Djokovic and Andy Murray.
However, they will be competing in front of empty stands at what is usually a buzzing Billie Jean King National Tennis Centre.
The event is taking place inside a 'safety bubble' which includes rigorous testing and restrictions on movement of the players, their support staff and tournament officials.
