During the match between Gimnasia and Boca Juniors in Argentina, police used tear gas on spectators outside the stadium, resulting in at least one death.
On Thursday, police attempted to prevent supporters from entering the already crowded stadium by firing rubber bullets at them.
The game was called off after nine minutes, with fans spilling onto the pitch trying to escape the turmoil.
Buenos Aires security minister Sergio Berni confirmed there was one death and that they “died of cardiac arrest”.
Authorities at San Martin hospital in La Plata, the city where Gimnasia is based, also confirmed the death, of a 57-year-old man because of cardiac arrest as he was being transferred from the stadium to the hospital.
An estimated 10,000 fans were outside the 20,000-capacity stadium and unable to get in.
Berni said an investigation would be opened, with the possible over-selling of tickets in one area being looked at.
Fans were squeezing through fencing to try to get onto the pitch of the Juan Carmelo Zerillo stadium in La Plata.
Referee Hernan Mastrangelo said: “It affected all of us on the field.
“The air became unbreathable. The situation got out of control and there were no security guarantees.”
The events in Argentina took place in the wake of the recent tragedy in Indonesia when at least 131 people died.
The disaster in Indonesia happened when police fired tear gas at fans who invaded the pitch after a game and hundreds tried to flee through the exits, which caused a deadly stampede.
