After Rollins issued a challenge for Mysterio's United States Championship for the December 23 episode of Raw, Mysterio cut a brief promo, using Spanish-language profanity, on Rollins and accepted the match.
Earlier in the show, Rollins, alongside AOP, attacked Mysterio. Mysterio was supposed to know who the No. 1 contender to his United States Championship was going to be in a Gauntlet Match, but Andrade hit a Hammerlock DDT on Humberto Carrillo on the concrete floor, ending the match without a definitive winner. This eventually led to Rollins' attack on Mysterio.
