The upcoming Liga BetPlay clash between Atlético Nacional and Millonarios brings a notable officiating assignment, as Dimayor confirmed that FIFA referee Diego Ulloa will take charge of the match at the Estadio Atanasio Girardot in Medellín. The high-profile fixture, slated for Saturday, September 27, at 8:30 p.m. local time (UTC-5), carries significant weight for both sides as they navigate the tournament’s 13th round.
Officiating Crew and VAR Assignments
According to announcements from tournament organizers, Ulloa will lead the officiating team on the pitch in Medellín. The referee from Valle del Cauca will be supported by assistant referee one Cristian Aguirre from Caldas and assistant referee two Jhon Aguilar from Risaralda, while Javier Villa from Antioquia serves as the fourth official, as reported by Win Sports.
The video assistant referee booth will feature Ricardo García from Santander as the main VAR official, complemented by Diego Ruiz from Meta acting as the AVAR, per league confirmation reported by Deportes RCN. The broadcasting rights for the match are held by Win Sports, with audio coverage available via Antena 2 and LAFM.
Statistical Context: Nacional’s Undefeated Run Under Ulloa
Statistical records highlight a striking trend regarding Atlético Nacional’s history with the appointed referee. As detailed by Win Sports, the Verde club has never lost a match officiated by Ulloa, who holds a FIFA badge. Across eight previous encounters directed by the official, Nacional has secured six victories and two draws, split evenly with three matches played at home and five away.
During those eight fixtures, Ulloa has issued 29 yellow cards and five red cards to Nacional players. His assignments involving the club earlier this year include a 4-0 victory over Once Caldas, a 1-2 defeat against Santa Fe, and a 0-0 draw with Deportes Tolima.
Millonarios’ Record and Technical Setup
On the opposing side, Millonarios’ historical numbers under Ulloa’s whistle also lean positive despite a singular blemish. According to Win Sports, the Embajador side has suffered just one defeat across 13 matches with the referee, recording five wins and seven draws in total. That span includes eight home fixtures and five away matches, though the club has yet to secure an away victory under his direction.
Ulloa has shown 38 yellow cards and two red cards to Millonarios players historically. In 2025, he has overseen two of their league outings: a 2-0 win against Deportes Tolima and a 3-0 victory over Junior de Barranquilla.
League Standing and Team Context
The encounter arrives at a critical juncture for both squads in the Liga BetPlay 2025-2 campaign. Deportes RCN notes that Atlético Nacional enters the fixture aiming to consolidate its position following a managerial transition that saw Diego Arias take over coaching duties in an interim capacity following the departure of Javier Gandolfi. Meanwhile, Millonarios arrives at the Atanasio Girardot seeking to maintain momentum within the top eight qualification zone after earning a home victory against Fortaleza in the previous round.
