Four-time Olympic gold medallist Serena Williams has confirmed she will not play in this summer's delayed Tokyo Games.
The 39-year-old American, who made her Games debut at Sydney in 2000, made the announcement in her pre-Wimbledon media conference on Sunday.
"I'm actually not on the Olympic list - not that I'm aware of. If so, then I shouldn't be on it," she said.
Williams did not want to elaborate when asked more about the decision.
The 23-time Grand Slam singles champion had already indicated she did not want to travel to Tokyo because she could not take three-year-old daughter Olympia with her under Games restrictions.
