Dyer took to social media to tell her fans about the development, holding back tears as she did so.
She said: “Hi guys, I’m going to do this, and try and do this without crying, but yeah, I’m so heartbroken, like I’ve not felt like this in such a long time.
“I was having the best time ever … It’s just [a] very, very annoying, devastating thing that I’m kind of going through right now, but I’m probably just going to have a few days off my socials just to, you know, process things.”
In a statement earlier in the day, she said: “I had a fall on Friday in rehearsals and landed funny. I thought I had rolled my foot but it swelled up badly over the weekend and after an MRI scan yesterday, it turns out I have fractured my ankle.”
