The referee who granted Once Caldas a controversial penalty to Boyaca Chico in last weekend's match was banned for five matches Wednesday.
Sebastian Valencia caused an outcry when he gave Once Caldas a 76th-minute penalty against Boyaca Chico after striker Ariel Carreno went tumbling over in the penalty.
Johan Fano converted to give Caldas a 2-1 win in the Colombian championship semi-final Group A game.
Boyaca had one player sent off for protesting and the team threatened to walk off the field.
Boyaca's leading shareholder Eduardo Pimentel later threatened to pull his team out of the championship and demanded foreign referees, a suggestion which has been ruled out by the Colombian Football Federation (FCF).
"This was an incident in which (referee) Valencia had direct responsibility," Fulton Vargas, head of the FCF's refereeing committee, told reporters.
However, Vargas also threatened to take legal action against Pimentel, who he said had repeatedly attacked the committee.
Carreno fuelled the controversy when he described the award as a present, although he implied that it was not a dive.
"When they gift you something like that and you haven't been looking for it, well that's good," the Argentine told the Citytv television station in an interview.
