Your picture didn't show up, but he definitely needs a vet either way. We can't say much about a lump from a picture - it could be a tumor, an abscess, or something else. It would be a good idea to get him into the vet ASAP tomorrow to get it checked out & see what's going on. Good luck, I hope it ends up being the easiest option to fix.
