Simone Biles revealed a terrifying health scare on Instagram, writing on Saturday that “almost dying wasn’t on my bingo card” and calling it “one of, if not the scariest experience of my life.”

Biles, who noted that she values her privacy and typically wouldn’t share an update like this, posted a series of photos on her Instagram Stories. The images included hospital bracelets, flowers, and a bed where the gymnast had been resting.

The 29-year-old, an 11-time Olympic medalist, also revealed that the medical emergency occurred while her husband — Indianapolis Colts safety Jonathan Owens — was at practice in Indianapolis.

In one photo, Biles showed her arm with what appeared to be three hospital bracelets. In another, she shared an image of her hospital bed alongside a screenshot of her heart rate reading 126 beats per minute.

It remains unclear whether the health scare was related to her heart.

“I’ve been in bed resting this week,” Biles wrote. “I’ll explain sooner or later but s/o to my close circle who reached out, checked in, visited & or sent flowers.”

Biles won four medals, including three golds, at the 2024 Paris Olympics. She and Owens married in 2023.
