The draw for the Clausura 2018 Copa Corona MX was held on Friday, with the 27 participating teams seeded into three pots for the draw based on their positioning in the Liga MX and Ascenso MX league tables.
The only caveat to the draw is that each of the nine Copa MX groups must have at least one team from each league; no group can contain only Liga MX or only Ascenso MX teams.
The final draw is as follows:
Group 1: León, Venados, Cafetaleros
Group 2: Cruz Azul, Alebrijes, Puebla
Group 3: Monterrey, Correcaminos, Dorados de Sinaloa
Group 4: Toluca, Mineros, Santos Laguna
Group 5: FC Juárez, Lobos BUAP, Pumas UNAM
Group 6: Zacatepec, Necaxa, Murciélagos
Group 7: Tampico Madero, Atlas, Veracruz
Group 8: Celaya, Pachuca, Atlético San Luis
Group 9: Monarcas Morelia, Cimarrones, Querétaro
