The conflict began during the interval of the match, with members of Vasco's technical committee and staff making offensive comments and attempting to physically assault the referee team. The police were required to intervene to contain the situation.
According to the summary report, Vasco's performance coordinator, Daniel Felix, approached the referee team in a "coarse and offensive" manner, questioning the expulsion of Barros and blocking the path of the referees.
Felipe Loureiro and Nelcirio Franchin, Vasco's director and goalkeeper coach, respectively, were also involved in the conflict. Loureiro allegedly repeated the phrase "hit my hand, c...!" while Franchin called the referee a "coward, son of a...".
The situation continued to escalate, with Franchin attempting to punch the fourth referee. He was again contained by the police before he could make contact.
After the match, Admar Lopes made a statement criticizing the referee team, accusing them of having a history of poor performances and making errors in the match, including the expulsion of Barros and a missed penalty in the area.
Lopes also requested that the referee be removed from the match in the return leg, citing the need for "fairness" in the competition.
