This is terrifying footage ...
A goalkeeper in a Bolivian soccer match was attacked by a fan who threw a firecracker from the stands during a match Sunday ... and the player was so frightened, he collapsed to the ground in fear.
The match took place at Estadio Hernando Siles in La Paz -- where a team called The Strongest took on the Jorge Wilstermann squad.
During the very end of the match, someone ran down close to the pitch and threw a firecracker at Strongest's goalkeeper, Daniel Vaca ... who covered his face and immediately fell to the ground.
