Roughing up his coach and teammate earned Impact midfielder Sandro Grande a ticket out of Montreal on Monday.
The United Soccer League First Division team released the 31-year-old nine days after Grande applied a chokehold to player-coach Mauro Biello during a 3-0 road loss to the Minnesota Thunder.
"Sandro's act was completely unacceptable and our organization does not tolerate such behaviour," Impact president Joey Saputo said in a statement Monday. "We have therefore taken the necessary disciplinary measures.
"Regardless of the circumstances or the player involved, violence is not accepted in our club."
Grande, who had already been suspended for his actions, also took a seat in May for breaching an unspecified team rule.
He had started nine of 14 games leading up to the latest incident.
