Allyson Felix one step closer to making history

U.S. sprinter Allyson Felix finished second in her heat and advanced to the finals of the women's 400m, putting her one step closer to reaching a record 10 Olympic medals.

If Felix medals in the 400m, she would have the record for most medals of any female track and field athlete with 10. If she also wins a medal in the 4x400m relay, she would surpass legend Carl Lewis with the most track and field medals ever. The Tokyo Games are the fifth Olympics for the 35-year-old track star.

Belarusian sprinter Krystsina Tsimanouskaya leaves Tokyo for Vienna

Krystsina Tsimanouskaya left Tokyo for Vienna, Austria, after spending the last two nights at the Polish embassy where she was granted a humanitarian visa.

Tsimanouskaya said she was excluded from her events and hustled to an out-bound flight by her Belarusian Olympic committee after she criticized them on social media. The Associated Press reported that Belarusian Olympic officials hinted she would face punishment upon her return home.

Tsimanouskaya never boarded the Belarus-bound flight after she hailed airport police and was put under their protection at the Haneda airport.
