Serena Williams announced that she will not participate in the Olympic games this summer in Tokyo on Sunday.

Williams told reporters at Wimbledon that he had her reasons for pulling out of the 2021 Summer Olympics; however, she is choosing not to make it public, according to Bleacher Report. 

“There’s a lot of reasons that I made my Olympic decision,” she said. “I don’t really want to – I don’t feel like going into them today. Maybe another day. Sorry,” Williams said. “I have not thought about it. In the past, [the Olympics] has been a wonderful place for me. I really haven’t thought about it, so I’m going to keep not thinking about it.”

Williams last competed in the 2016 games in Rio De Janeiro, but she did not bring home any medals. Still, she is one of the most successful Olympic tennis players of all time. She won singles gold in 2012 and doubles gold with her sister, Venus Williams, in 2000, 2008, and 2012. Only her sister and Britain’s Kathleen McKane Godfree have taken home more Olympic tennis medals, with five each.

Williams is still the eighth-ranked women’s tennis player in the world, according to ESPN. She will be looking to add her eighth Wimbledon title and 24th Grand Slam to her list of accolades when she plays Aliaksandra Sasnovich of Belarus on Tuesday.

This will be the first time surfing will be included as a competitive sport in the Summer Olympics, and 22-year-old surfer Katherine Diaz was looking forward to participating in them. Unfortunately, last Friday, the 22-year-old was struck by lightning in the southwest region of El Salvador. According to People and multiple outlets, the storm was not expected, and it was a sunny day.

According to People, Diaz was training at El Tunco beach when she was struck. People passing by tried to help before the paramedics arrived, but Katherine had already passed away. On Twitter, The International Surfing Association (ISA) responded to Diaz’s death.

“Katherine embodied the joy and energy that make surfing so special and dear to us all as a global ambassador of the sport. She excelled at the int’l competition level, representing her country with pride at both the World Surfing Games and ISA World Jr Surfing Championship.”

At the time, Katherine’s uncle, Beto Diaz, was with her when she was killed. “Upon reaching the beach, Katherine met a German friend, who was also going surfing at the time,” said Beto. “Katherine approached to hug her; as soon as she finished hugging her, the noise was heard. She, the friend, was thrown by the force of the lightning strike too; the board threw me. Katherine passed away instantly.”
