I would think though, just remove cut card and use next card.

Roberts rules of poker: Sect: irregularities 3. If a card with a different color back appears during a hand, all action is void and all chips in the pot are returned to the respective bettors. If a card with a different color back is discovered in the stub, all action stands. 8. A joker that appears in a game where it is not used is treated as a scrap of paper. Discovery of a joker does not cause a misdeal. If the joker is discovered before a player acts on his or her hand, it is replaced as in the previous rule. If the player does not call attention to the joker before acting, then the player has a dead hand Not quite sure which one applies here though??? good luck deciding
