What happened: A young U.S. women's gymnastics squad is set to compete at the World Championships while Simone Biles sits out the event. Several past Olympians are already targeting a comeback for the 2028 Los Angeles Games.

Why it matters: Biles has not yet committed to joining the push toward the home Olympics in Los Angeles. The current World Championships give the incoming American roster major international experience during the buildup to 2028.

What to watch: World Championships competition begins as the young U.S. lineup takes the floor.
