Chalice coral detached from skeleton

[Zakary2003]

I have a TSA Avatar chalice coral that grew to a decent sized colony and then died back substantially after a tank crash. Now, months later, the tiny section that survived was looking better until it fell into the sand yesterday. Today it detached from the skeleton. Is there any way to reattach it or save it?
