Uruguay's football association has sanctioned first-division club Fenix after two chickens were let loose on the pitch in a game against Racing on Sunday.
The incident has also made club director Gaston Alegari a target of criticism from animal rights groups and fans after he violently kicked the chicken off the pitch.
Alegari took to Twitter on Monday to apologise for his behaviour.
Lamento los hechos ocurridos en el día de ayer. Esa no es mi forma de actuar. La situación del momento me llevo a reaccionar de forma desmedida e inadecuada. Pido disculpas públicas por mi accionar.— Gaston Alegari (@gastonalegari) March 12, 2018
"I'm sorry for the events that happened yesterday," he wrote. "That's not my way of acting. The situation of the moment led me to react in an unmeasured and inadequate way. I want to publicly apologise for my actions."
The Uruguayan association decided on Tuesday that Fenix will have to play one match away from their home stadium because of the incident.
The two chickens were painted in white and green, the colors of Racing.
Racing won 1-0 after scoring five minutes before the final whistle.
