Liga MX had previously introduced a mechanism for relegated teams to remain in the first division, which also introduced new requirements for Ascenso MX teams to be eligible for promotion – namely, economic stability, proper infrastructure, and the ability to field teams in the various youth divisions as well as Liga MX Femenil.
In the first season after the new process was introduced, the Ascenso MX champion – Cafetaleros de Tapachula – was not eligible for promotion, while the relegated Liga MX team – Lobos BUAP – paid the required 120 million pesos to remain in the first division.
This year, however, the Ascenso MX champion was one of the nine teams in that division certified for promotion. Atlético San Luis won promotion to Liga MX after winning the Ascenso MX title in both the Apertura 2018 and Clausura 2019 seasons.
But the relegated team, Veracruz, was still able to “fulfill all the requested requirements” to remain in the first division, despite finishing the Clausura 2019 with zero points after suffering a FIFA mandated six-point deduction for unpaid debts.
Therefore, following the league’s Regular Assembly in Toluca, it was announced that Liga MX will have 19 teams for the 2019-2020 season. The odd number of teams means that one club will have a bye each week.
The Apertura 2019 season is slated to begin on July 19th and run through December 15th, with the full calendar to be announced.
