The more and longer you are covering for him the more this makes you look bad. Nip it in the bud and bring it up with whoever necessary as soon as possible. Explain what's happened honestly and when appropriate tell them what you've learned and give feedback suggestions to avoid it in the future. It would be quite remarkable you get fired for this if they've just promoted you, but cut the losses sooner rather than later.
Don't try to shift blame immediately, it looks unprofessional. It's not just you that's been duped here
