Archaeologists in Mexico say they have uncovered three ancient playing fields at a pre-Hispanic site in the eastern state of Veracruz.
They found the courts, dating back some 1,000 years, at the Tajin World Heritage site by using laser scanners.
They believe the fields would have been used to play pelota, a game in which players used their hips to propel a rubber ball through stone hoops.
The sport was widely played by Mayan and other pre-Columbian people.
Experts from the National Institute for Anthropology and History (INAH) said the use of aerial photography, remote sensors and laser scanners had made it possible to find the ancient structures, hidden by layers of soil and dense vegetation.
