Simone Biles set to return to competitive gymnastics after two-year absence

Seven-time Olympic medalist Simone Biles is due to return to competitive gymnastics on Saturday for the first time since pulling out of several events at the Tokyo Olympics in 2021.

Biles is registered to compete in all four events at this weekend's Core Hydration Classic - previously called the US Classic - a spokesperson for USA Gymnastics told CNN.

Saturday will mark the 26-year-old Biles' first competition since August 2021 when she withdrew from the women's team final in Tokyo after suffering from what is known as the "twisties" - a mental block that causes gymnasts to lose track of their position in midair.

Biles opted not to compete in four individual finals at the Games, but she did return to compete in the balance beam, winning bronze after using a modified dismount in her routine.

The Core Hydration Classic, which will be held in the Chicago suburb of Hoffman Estates, is the final opportunity for athletes to qualify for the national championships in San Jose, California, later this month.

The world gymnastics championships are then scheduled to take place between September 30 and October 8 in Antwerp, Belgium.

A sellout crowd is expected on Saturday at Hoffman Estates, where spectators will be eager to not only see Biles' much-anticipated comeback, but also the likes of returning Olympic gold medalist Sunisa Lee.
