Has this coral died

[Kylepope2020]

Hi guys, I was doing tank maintenance and scraping my glass the other week & the back of my hand scraped across my candy cane coral quite hard and I’m just wondering have I killed it ? As it’s not looking too great the first picture where the coral is full of colour is when I first got it about 2 months ago and the other two are today the coral is looking as if it’s turning white around the top and the colour just isn’t there anymore

It’s tissue recession from being upset
Provide moderate light and water flow and mid tank is best location
