Atletico Rafaela coach Jorge Burruchaga was sent off before his team's 2-1 loss at Boca Juniors in the Argentina Primera Division.
Referee German Delfino dismissed Burruchaga after he deemed Rafaela's entrance to the playing field to be too late.
Veteran Juan Roman Riquelme put Boca ahead with a sharp strike on 30 minutes before Lucas Albertengo levelled the contest four minutes before half-time.
But Boca had the last laugh over their coach-less opponents as Emanuel Insua struck the winner in the 68th minute.
The win lifted Boca into third position, behind leaders Argentinos Juniors and Gimnasia La Plata on goal difference.
Argentinos enjoyed a crushing 3-0 win at San Lorenzo, who recorded their first loss of the campaign.
Defender Julio Barraza got the first goal on 11 minutes with striker Hernan Boyero scoring nine minutes after half-time.
Rodrigo Gomez scored the third in the 64th minute, capping a great victory for Argentinos.
Gimnasia were buoyed by an opening-minute own goal as they went on to record a 3-1 triumph at home against Rosario Central.
Paulo Ferrari's unfortunate moment kick-started Gimnasia and they managed to double their lead through Federico Rasic after 19 minutes.
Rosario pulled a goal back through Franco Niell in the 38th minute but the points were wrapped up for Gimnasia by a Ignacio Fernandez strike on 84 minutes.
A brace from Sergio Araujo propelled Tigre to a comfortable 3-1 win over 10-man Racing Club.
In other results, Arsenal kept Olimpo's winless start to the season in motion with a 3-1 victory, two goals in the first 10 minutes saw Lanus draw 1-1 with Estudiantes and there was a goalless draw between Godoy Cruz and River Plate.
All Boys and Velez Sarsfield fought out a 1-1 result, Colon shaded Quilmes 1-0 and Newell's Old Boys were locked 0-0 with Belgrano.
