Serena Williams says she intends to play at the behind-closed-doors US Open in August and bid for a record-equalling 24th Grand Slam.
The event will be held without fans in New York from 31 August, despite some players voicing concerns.
But Williams, 38, said: "I really cannot wait to return to New York and play the US Open 2020."
The ATP and WTA Tours, suspended since March because of the coronavirus pandemic, will resume in early August.
This year's Wimbledon Championships were cancelled for the first time since 1945 as a result.
The US Open will be the first Grand Slam to take place since the pandemic, with the United States Tennis Association (USTA) saying the decision to hold it without fans was "not easy" but the "correct one".
