Cannot remove description field after adding to the Custom List

Question

Hello,
Applies To: SharePoint 2013
Problem: We created a Custom List and added a Description column from "Add from existing site columns" link. Now we need to remove it and it seems to have been sealed. We are not able to delete it.
There is no remove/delete link/button when we click on the field. Moreover in the Content Type it only shows Required, Optional, Hidden.
Requirement: Need to remove this field from the Custom List. Incidentally we added two of the description fields. We need to remove both of them without deleting the list itself.
Thank you and
Regards

Hi Tanzim,
Try the following code. I tested it and it should work for you.
Add-PSSnapIn Microsoft.SharePoint.Powershell
$web = Get-SPWeb "Web URL" 
$list = $web.Lists["List Name"] 
$field = $list.Fields["Description"] 
$field.AllowDeletion = $true
$field.Sealed = $false
$field.Delete() 
$list.Update() 
Remove-PSSnapIn Microsoft.SharePoint.Powershell
