I've been thinking about this over the past few days and I can't see Leila lying about the injury.
I read somewhere that she wouldn't have kept her Ugg boots on while going to the hospital, it would have kept her ankle supported (mind you I have had to throw my Ugg boots away after slipping over in Birmingham last week, they can be really slippy), she was trying to dance on 3" heels with all of her weight on her ankle, in a dance where the twisting and turning puts even more pressure on her ankle, so cut her a little slack. I've sprained my ankle a lot in the past and tore my ankle ligaments and I couldn't even walk properly, or get a shoe on let alone get into 3" heels and try and dance a Rhumba, I still suffer now after years of spraining ankles so it's not as insignificant as people think.
I am not a great fan of hers, find her a little moany but think she is getting a lot of bad press here, along with Jade who I hope will be ok and able to continue her athletics career.
