Serena Williams, who will be turning 40 in September, said on Sunday that she will not be joining the Olympics, albeit no reason was given.

Williams, won the singles title at the London Olympics in 2012 and she has also picked up three gold medals in doubles with sister Venus – in Sydney (2000), Beijing (2008) and London.

Williams joins the likes of other players such as Rafael Nadal and Dominic Thiem, who opted to skip the Tokyo Games. Roger Federer will however make his decision after Wimbledon.

“Yeah, I’m actually not on the Olympic list, so … Not that I’m aware of. If so, then I shouldn’t be on it,” Williams told reporters on the eve of Wimbledon. “There’s a lot of reasons that I made my Olympic decision,” Williams said. “I don’t really want to … I don’t feel like going into them today. Maybe another day. Sorry. In the past it’s been a wonderful place for me. I really haven’t thought about it, so I’m going to keep not thinking about it.”
