River arrives in Bogotá on Wednesday with a changed defense and no margin for error. Eduardo Coudet has been forced to reshuffle the back line for the first leg of the Copa Sudamericana 2026 round of 16 against Independiente Santa Fe at Estadio El Campín, with Gonzalo Montiel, Marcos Acuña and Sebastián Driussi all out.
The match starts at 21:30 in Argentina and 19:30 in Colombia, with carrying it live and Disney+ Premium streaming it online. For River, the timing matters as much as the opponent: the tie opens away from home, in a knockout round, and the return leg is next week at Estadio Monumental.
Coudet’s emergency plan points to Lucas Martínez Quarta at right back, Facundo González at left back, and Nicolás Otamendi with Lautaro Rivero in the middle. Thiago Almada, who has a contracture, is expected to begin on the bench. It is the kind of lineup that tells the story before a ball is kicked: River is still strong enough to travel with ambition, but not intact enough to pretend this is ordinary.
That challenge is sharper in Bogotá, where Estadio El Campín sits about 2,600 meters above sea level. River has won only one of its last five matches played at altitude, with one draw and three losses, a record that explains why this trip is being treated as more than just another away fixture. Even after beating Argentinos Juniors 2-0 in the Torneo Clausura before leaving for Colombia, River enters a setting that has repeatedly exposed thin squads and unsettled plans.
The friction for Coudet is not only the missing names. It is the mismatch between a team that just picked up a clean win and a match that demands caution, stamina and defensive order from the first minute. Santa Fe gets the first shot at turning the tie on its head in Bogotá, while River has to survive the altitude, protect a patched-up back line and keep the second leg at Monumental within reach. If the makeshift defense holds, River can take control of the round; if it cracks, next week’s return may already feel like a rescue mission.
