Olympian Gabby Douglas was hospitalized twice for an infection stemming from a past mouth injury.

“Gabby is back in the hospital tonight being treated for a seriously infected past mouth injury,” her rep told Page Six on Sunday night. “She continues to have deep swelling and adverse reactions to medications.”

She was forced to skip the evening’s MTV Video Music Awards, where she and the rest of the Final Five gymnasts were slated to present together.

Reaching out to her fans earlier on Sunday, Douglas said she was “out of the hospital & resting comfortably.” #FinalFive so sad I can't be with u all to present tonite," she said on Instagram.

But Douglas’ rep later confirmed that the athlete had to return to the hospital after the social media post.

The 20-year-old’s gymnast pals Aly Raisman, Madison Kocian, Laurie Hernandez and Simone Biles all attended the awards show and publicly wished Douglas well wishes during their time on stage. Olympic champ Michael Phelps also made an appearance at the show, introducing a performance from the rapper Future.
