Atlético Huila were the defending champions, having been unable to earn promotion to the Categoría Primera A despite winning the previous tournament.
In the Torneo I, the 16 teams played a single round-robin tournament under the same fixture as the previous season, but with reversed home-and-away order.
However, video footage of Unión Magdalena's winning goal appeared to show the Llaneros players backing off and failing to make an effort to prevent their rivals from scoring.
[6] The events sparked outrage both within the country and abroad, with Colombian internationals Juan Cuadrado and Mateus Uribe expressing their displeasure, calling them "a lack of respect" and "an embarrassment for Colombian football", whilst President of Colombia Iván Duque Márquez stated it was a "national disgrace".
[7][8][9] In response to the growing backlash, as well as calls from Fortaleza to get the match annulled and Unión Magdalena's promotion reversed,[10] DIMAYOR chairman Fernando Jaramillo ordered the opening of an inquiry on the match events while also requesting the Office of the Attorney General of Colombia to investigate whether any criminal offenses had been committed,[11][12] but on 7 December 2021, Jaramillo stated that the tournament would not be paused and Unión Magdalena's promotion would not be overturned while due process was completed.
[14] On 30 December 2021 DIMAYOR's Disciplinary Commission closed the investigation on Unión Magdalena as it found no evidence implying that members of the aforementioned club had been responsible for the events that occurred in the match against Llaneros, thus confirming their promotion to Primera A.
