Former Rangers boss Pedro Caixinha's club have been rocked by a player's admission of match fixing.
Red Bull Bragantino defender Kevin Lomonaco confessed to being purposely booked against America in November.
Lomonaco was one of four players who confessed to the Public Ministry of Goias to have participated in a match manipulation scheme.
The crime could see offenders sentenced to six years in prison but the players involved were offered a non-prosecution agreement, UOL Sport reports.
Lomonaco was not prosecuted over the match fixing scheme and became a witness to the investigation into match fixing in Brazil.
In his confession, Lomonaco said: "I was in concentration the day before the game, I guess.
"He kept insisting, texting, saying, 'Let's close, hermano, it's money...'
"I kept talking to him at the rally, and then yes: we got a yellow card.
"But I did it without any knowledge that it was a crime or something.
"I did it like that, I didn't ask anyone anything."
The defender was reportedly set to earn R$70,000 in return for being booked in the match but was only paid R$30,000 for his role in the match manipulation scheme.
However, Lomonaco claims he was unaware what he was doing was a crime and insists he only went through with it because he didn't think his actions would have any consequence to his team.
Lomonaco said in his confession that he was approached for further involvement in conceding penalties or being sent off but said "it wasn't my intention to do that".
He added: "I did the yellow only because I thought it wasn't something that hurt the team.
"I thought it was something normal and I didn't think it was a crime, anything like that.
"It was like I said, I didn't ask anyone anything, I did it for the sake of doing it, then in a moment, it was a quick day there, just."
