Firefighters say Monday at least 111 people were hurt - 22 critically. They have been taken to hospitals after the accident in Brazil's southern Parana state.
At least 500 people were sitting in the section of bleachers that collapsed Sunday.
Authorities say they think the bleachers had structural faults that caused the collapse. But a police investigation must end before a definite cause can be determined.
