Athletes to follow during the 2020 Olympic Games

The long-awaited 2020 summer Olympics in Tokyo have officially begun following a pandemic pushback that postponed the Games for one year. Although in-person spectators won't be allowed due to a state of emergency prompted by COVID-19 in Japan, there is still plenty to look forward to this year, as multiple Olympians have the potential to make history.

Keep track of these eight standout stars at this year's competition with the following schedules, and find more coverage at CBS Sports. All events are tentative and listed in Eastern time. Live coverage of the events will air live on Peacock and re-air on NBC, NBCSN and USA.

Osaka took a break from competition this summer after she withdrew from the 2021 French Open to protect her mental health. She skipped Wimbledon in 2021 as well, but she'll return to the courts vying for Japan's first gold medal for tennis at the Olympics.
