Please tell me I don't need to replace the door. I'm really not sure how this happened. Just worn out?

 

looks like it was slammed a time or two.....well you can either replace the door.....or if your good with metal and welding....fab something up...thats what i would do...but if your posting this asking if you need to replace the door or not im assuming you dont fabricate, otherwise you would have already thought of that
