They advanced and faced Club León in semi-finals. The first match was played in the Nou Camp in León, with a score of 2–0, with Leon taking home advantage. The second match was played in Puebla in the Estadio Cuauhtémoc, with over 45,000 Puebla supporters. That game ended in a 3–3, in a match that is still talked about today, and that some speculate has started a riverbed between these 2 clubs. Puebla waited for the champion of the Clausura 2007 that would be disputed by Club León and Dorados de Sinaloa. Dorados would be that champion 4–5, and so faced Puebla in a promotional match to determine the club that would be promoted to the first division. The first match was played in the Estadio Carlos González in Sinaloa. The game would finish in a 1–1 draw. Scoring for Puebla was the lead scoring champion Álvaro González, and Carlos Casartelli for Dorados. The second game was played on Sunday 26 May 2007, in a packed Estadio Cuauhtémoc, with over fans, which the club later would be cited for being over-capacity.
