In the first leg of the Copa Sudamericana semifinals between Boca Juniors and Vasco da Gama, held in Argentina, Vasco da Gama lost narrowly but raised concerns over the officiating by referee Piero Maza. The Chilean referee showed two yellow cards to Colombian player Andrés Gómez of Vasco da Gama in the 64th minute, leading to his expulsion. This prompted Vasco da Gama to consider filing a formal complaint with CONMEBOL, citing Maza’s repeated officiating of Boca Juniors at home and previous controversial decisions, such as allowing Boca to take kickoffs against Recoleta and failing to correct a red card for a Sao Paulo player via VAR. Multiple media outlets, including Bolavip Argentina, ESPN, TyC Sports, and Lance!, criticized Maza’s performance, describing the ejection of Gómez as 'insulting' and 'unusual.' The return match between the teams is scheduled for October 20.
