Atlético Nacional have defeated league leaders Deportes Tolima with a last gasp winner from Córdoba, and find their way into the top eight.
Atlético beat leaders
Tolima were on their way to yet another win with a Marangoni goal in the 31st minute but Perea equalised for the home side seven minutes later.
The winner came at four minutes from the end, when Cordoba beat the opposing goalkeeper for 2-1.
Tolima do maintain their lead, but three other teams follow at only one point. Atlético are now shared seventh, together with Deportivo Pereira.
No goals at El Campín
Santa Fé failed to take advantage of Tolima’s slip-up and were held to a goalless draw by Atlético Bucaramanga in Bogotá.
Consequently, Santa Fé are one of the three teams trailing Tolima by one point. The other two are Junior Barranquilla and Millonarios.
Bucaramanga have a good chance of making it to the next round as well, currently being placed sixth in the league.
Once Caldas held by Quindío
Once Caldas dropped a few spots after a 1-1 draw with Deportes Quindío in Manizales.
Ciciliano, who recently made a move from Millonarios, put the home side in the lead but Santoya levelled the score shortly after the hour mark.
Caldas now occupy the fifth position while Quindío, placed tenth, continue to fight for a top-eight spot.
