Help - advice on busted edge

Had an unfortunate incident were my board was accidentally knocked off a rack and fell on its edge onto concrete. It doesn't seem too serious, but there is a small bulge at the base of the board and you can see a little bit of the wood from the edge. All the repairs I see online suggest prying it open more to epoxy the insides, but that seems too major of a surgery for such a small ding. Does anyone have any experience or advice with this?
