LOS LLANITOS (AP) — On a dirt field on Mexico's Pacific coast, five cousins between the ages of 8 and 13 strip down and kick off their shoes. Nearby, adults help them fasten the pre-Hispanic-style fajado, securing loincloths and leather belts that wrap around their hips.

The Osuna children grab the rubber ball, all 3.2 kilograms of it — around seven pounds or seven times heavier than a soccer ball — and begin playing. Only the hips may touch it, forcing players to leap through the air or dive low when it skims the ground.

As Mexico prepares to co-host the 2026 FIFA World Cup, the nation is looking back 3,400 years to one of the oldest team sports: the ancient ballgame known as ulama, a ritual practice nearly erased during the Spanish conquest that survived only in the remote pockets of northwestern Mexico before its late 20th-century rebirth. Today, authorities and its modern players are leveraging the momentum of international soccer to shine a spotlight on the ancient sport once again.
