The coupe only uses 2 bolts to affix the bumper assy to the extensions. Towards the rear (where the cover meets the fender) there is a slide mounted to the cover and a slide bolt mounted to the fender. As mentioned, you need to remove the bumper assy to determine if there is any damage. It is possible that a front minor hit either broke a slide or caused the slide bolt to pop out of the slide. The slides themselves are only mounted to the cover by a couple of clips and screws. You could also have had a slide become disconnected from the cover. Only way to tell is remove the bumper assy and inspect.
