"I used to play on an ollamaliztli team, a few years ago," Fede said. "Several of our matches were held in the tlachtli in Teotihuacán. I got to know the areas of the stadium that the public does not see, the sections used by the teams and their support staff. The key to getting into the adjoining temple is to access the first-aid rooms—the area where MedíCarro staff stabilize injured players before their transport to hospital. Because the priests sometimes come in to pray over the injured players, there is a connecting passage between the tlachtli and the teocalli ."
