The "Stranger Things" star talked about the nasty injury on her Instagram page. "I have split my kneecap", Brown said with her crutches in view. "From the doctor's orders, he told me to rest up".
The popular 14-year-old actress and the hit Netflix show are nominated for a total of six awards at the ceremony, which airs on Monday. "Love you guys so much and peace out!" "And I'll be there in spirit".
Millie, of course, announced on Instagram because she deactivated her Twitter account earlier in the week after being the subject of cyber bullying - users posted memes depicting the teen actress as homophobic.
The post comes days after the actress made a decision to delete her official Twitter accounts due to hateful comments and homophobic memes, some paired with the hashtag "Take Down Millie Bobby Brown".
Online trolls have been taking various selfies and media she posted on the account and photoshopping them with crude and homophobic captions created to make the star, who is pro-LGBTQ, seem to be violently against homosexuality. As Vanity Fair notes, the star wore a pin to the MTV Movie and TV Awards a year ago to support the Gay and Lesbian Alliance Against Defamation's "Together" movement.
