As previously reported, Gabby Douglas missed last Sunday’s MTV Video Music Awards (VMAs)  because she was admitted to a hospital due to an infection. At the time, Douglas’ publicist Lesley Burbridge told People that the Olympic gold medalist was treated for a serious infection of an old mouth injury. Now, Douglas herself took to social media to reveal the diagnosis of her medical condition.

“I had a complication from a prior injury that caused a cyst to grow on a bone in my mouth,” the 20-year-old gymnast wrote on Instagram, alongside a photo of herself lying on what appears to be a dental chair. “Got it removed and feeling much better now!”

In the latter part of her post, Douglas thanked her fans for their concern and prayers. She also expressed her gratitude to the doctors who have taken care of her for the last four days.

Douglas was supposed to join her Final Five teammates Simone Biles, Laurie Hernandez, Madison Kocian and Aly Raisman to present at the VMAs, but due to the said complication, she didn’t make it to the event.

“Something was a little swollen on her face,” Raisman told Entertainment Tonight on the VMAs white carpet when asked about Douglas’ condition on Sunday. “They’re having her rest, just in case.”

Hernandez, who noted that the infection wasn’t major, said: “It's a little bit swollen, but we hope she can get better soon because we wish she could be here with us."

“She definitely wanted to be here.” Kocian added.

According to People, Douglas is scheduled to appear on this Thursday's episode of “The Late Late Show with James Corden,” but it’s unclear whether the athlete’s doctors would allow her to move forward with her guest appearance.

Douglas is also set to appear as one of the judges at the Miss America 2017 pageant, which will be held at the Boardwalk Hall in Atlantic City, N.J., on Sunday, Sept. 11. Earlier this week, Douglas tweeted that she couldn’t wait for the event.
