The 1989 Campeonato Profesional was the 42nd season of Colombia's top-flight football league. The season was cancelled after 318 matches because of the assassination of referee ÃÂlvaro Ortega on October 1 in MedellÃÂn. No champion was declared and no teams qualified for international competitions for the following season (however Atlético Nacional played the 1990 Copa Libertadores as champion of the previous edition).
The season consisted in six phases. The first phase, Torneo Apertura, had a round-robin format. The second phase consisted in a Pentagonal (three groups of five teams each one, playing against each other at home and away). The third phase, Torneo Finalización, had a similar format that Torneo Apertura. The fourth phase, Cuadrangular Inicial, consisted in two groups of four teams each one, playing against each other at home and away. The others phases, Repechaje and the finals, were not played due to the cancellation of the tournament.
Teams received two points for a win and one point for a draw. If two or more teams were tied on points, places were determined by goal difference.
The Pentagonal, officially known as the Copa Colombia, was played as a mid-season stage of the league championship, with its results used to award bonus points to the top finishers in the overall standings.
Teams were divided into three regional groups. Points were given after teams played each other home-and-away. The top 8 of the overall standings qualified for the second stage.
Group A (Occidental)
Group B (Central)
Group C (Septentrional)
The following top 8 teams qualified to the second stage:
