Brazil captain Neymar lost control and verbally abused referee Enrique Osses in the aftermath of his side's 1-0 Copa America defeat versus Colombia on Wednesday.
The Barcelona attacker was shown a straight red card after an altercation with Jeison Murillo and Carlos Bacca after the final whistle and then waited for Osses in the tunnel to voice his dismay with the decision.
Neymar insulted the referee more than once as he lost his temper following his dismissal, with Osses keeping his calm and putting up an extra finger for each time the 23-year-old verbally assaulted him.
The Chilean referee's attitude angered Neymar and he attempted to lash out at the referee, only to be kept out of Osses' reach by Copa America officials. He allegedly called out: "You are trying to become famous at my expense, son of a b****!"
Brazil were initially hopeful Neymar would escape a severe punishment following his decision, yet Conmebol had no other option but to lay down the law on the former Santos star and ban him for four games after Osses included the incident in his match report.
Neymar's suspension means he will be out for the remainder of the tournament, even if Brazil make it to the final.
