Liga de Expansión MX

The Liga de Expansión MX, officially known as Liga BBVA Expansión MX for sponsorship reasons, is a Mexican football league founded in 2020 as part of the Mexican Football Federation's "Stabilization Project", which has the primary objective of rescuing the financially troubled teams from the Ascenso MX and prevent the disappearance of a second-tier league in Mexico. The project also attempts for Liga MX and former Ascenso MX teams to consolidate stable projects with strong administration, finances, and infrastructure.

History
On 20 February 2020, the presidents of the Liga MX clubs, the Ascenso MX clubs and Mexican Football Federation executives had a meeting, in which different topics were discussed with the intent of strengthening the two main leagues in the country.

On 26 June 2020, the league was officially presented, with the participation of 16 teams: Alebrijes de Oaxaca, Atlante, Atlético Morelia, Cancún, Celaya, Cimarrones de Sonora, Correcaminos UAT, Dorados de Sinaloa, Leones Negros UdeG, Mineros de Zacatecas, Tampico Madero, and Venados F.C. as Ascenso MX teams. Pumas Tabasco and Tapatío entered to the league as Liga MX affiliates. Finally, on 17 July 2020, Tepatitlán and Tlaxcala were invited as Liga Premier expansion teams.

On 22 May 2023, the Liga MX owners assembly approved a reform for the league that should have been carried out in 2024. This reform planned that the 18 member teams of the Liga MX should have had a U-23 team in the Liga de Expansión, which would have represented a merger between the Expansión MX and the Liga MX U–23. However, in May 2024 the proposal was scrapped due to opposition from the owners of the Liga de Expansión teams, as they considered that the project represented a degradation of the participating clubs.
