Overview
- Club owners approved a one‑off rule allowing Liguilla qualifiers to register Mexican players from eliminated Liga MX teams to replace national‑team call‑ups.
- The reinforcements would be temporary and must return to their original clubs after the Liguilla if the measure is authorized.
- The package still requires FIFA approval before it can take effect for the Clausura 2026 tournament.
- Other proposed adjustments include permitting up to nine players not formed in Mexico to feature in the Liguilla and removing the Play‑In phase.
- The schedule is set to compress with a January 9 start and three double matchdays to finish before the 2026 World Cup, with operational details of the new rule still to be defined.
