Castrillón, who wore the No. 10 shirt, collapsed on Saturday, during a national youth championship match against rivals Independiente Santa Fe.

Promising career cut short
Originally from Bucaramanga, Castrillón had been part of Millonarios’ academy since 2021 and was seen as one of the club’s brightest prospects.
He had regularly trained with the senior team and received his first official call-up for a top-flight match in October 2025, proving his rapid development.
Millonarios expressed deep sorrow in an official statement, saying the “blue heart is broken” following the loss of one of its young talents.
Tributes also came from across the football community, including Colombian striker Radamel Falcao, who shared condolences and support for the player’s family.
The incident comes nearly two years after the death of Guillermo Denis Beltrán, who passed away in March 2024 at the age of 24 after suffering a respiratory arrest during training in Bolivia.
