Four-time Olympic gold medalist Simone Biles is set to compete at the 2021 U.S. Classic on May 22 in Indianapolis, marking her first competition in more than 18 months. The event will air live on NBCSN at 7 p.m. ET.

The early session of the U.S. Classic will stream at 1 p.m. ET on Peacock, then at 5:30 p.m., Peacock will host an exclusive warm-up show with live look-ins at Biles' warm-up session. Terry Gannon will handle play-by-play duties for the NBCSN coverage, while Olympic medalists Nastia Liukin and Tim Daggett will serve as analysts.

The 24-year-old Biles last competed at the 2019 World Gymnastics Championships, where she won five gold medals and landed two new signature moves. Since then, she's developed a vault that no woman has attempted in competition, a Yurchenko double pike, and has said she plans to debut it before the Olympics.

In addition to Biles, the U.S. Classic field is expected to include Sunisa Lee -- a three-time gold medalist at the 2019 World Gymnastics Championships -- Tokyo Olympic Games individual qualifier Jade Carey and 2016 Olympic medalist Laurie Hernandez. Adding to the intrigue, 2008 Olympian Chellsie Memmel, 32, is set to compete for the first time since 2012. 

The U.S. Classic is the final chance for female gymnasts to qualify for the 2021 U.S. Gymnastics Championships, scheduled for June 3-6, which in turn is a qualifier for Olympic Trials later in June.
