A power failure has forced the postponement of the international between Argentina and Brazil overnight.
The two sides were due to play the second leg of the Superclasico de las Americas in the Argentinian city of Resistencia, but an outage of half of the stadium's floodlights made it impossible for the match to go ahead.
Chilean referee Enrique Osses told America TV that the poor lighting presented a hazard to players.
"We were unable to see properly. I wanted to ask the goalkeepers, because they are the most affected players, and they told me they could not see well," Osses said.
"Nobody guaranteed the lights were going to be back quickly so we decided the match could not be played under these conditions.
"This is the first time something like this has happened to me."
Only players who ply their trade in Argentina or Brazil were due to feature, with Brazilian forward Neymar hoping to get some match time as he serves a one-match suspension for Santos.
After taking a 2-1 lead in the first leg of the tie, Brazil were eager to secure the title for a second consecutive year and coach Mano Menezes was left frustrated by the postponement.
"Big teams like Argentina and Brazil should not go through this type of problem," Menezes said.
"We have prepared a lot for this match. We obviously wanted to play. We always want to play.
"Now we have to call up the players again for this match in the future."
25,000 fans packed the Estadio Centenario ahead of kick-off and with players required back at their clubs for this weekend's fixtures, the match will not be rescheduled until at least next week.
