Chiapas F.C.
Eighteen teams competed in the season. Querétaro was relegated to the Ascenso MX after accumulating the lowest coefficient over the past three seasons. The 2012 Apertura Ascenso MX champion La Piedad would promote after defeating the Clausura 2013 winner Neza in a promotional play-off. But on May 28, 2013, Querétaro's ownership announced that it bought out Jaguares de Chiapas, relocated the team to Querétaro, dissolved the old Querétaro team and ensured that Querétaro would still have a team in the first division. It was also announced that San Luis would move to Tuxtla Gutiérrez and be rebranded Chiapas F.C., replacing the old Querétaro. La Piedad confirmed that they would relocate to Veracruz and be rebranded as Tiburones Rojos de Veracruz. These changes sparked controversy in the Mexican press as Querétaro effectively bought its place back in the first division and newly promoted La Piedad completely lost its team.
