If you have a recent backup of your gradebook, you can retrieve it. And, it's possible that your district may have made a backup of gradebooks, too.
To check for a backup, select the Manage Gradebook option. Click the Restore tab on the far right. Check to see if you have any backups that would contain the assignment. If so, restore the gradebook and copy the assignment back into your gradebook. Otherwise, you will have rebuild the assignment.
