If bumper pulled up when I was trying to pull a stump out of ground. does that mean I just need to loosen bracket bolts & slide it back down?

I was trying to slowly pull forward in 4wd to pull out a stump in the ground using a chain wrapped around the hitch on my trucks bumper and the chain was going over a pile of dirt in the middle and I think that caused it to pull up my bumper, where it looks bent upwards now, but if the brackets are not bent (how would they look if bent? I know stupid question right?, but really would they maybe not look bent, but they are?)...maybe I just need to loosen the bracket bolts and slide the rear bumper back down and then retighten?
