Overview

• The single-elimination tie kicks off Thursday at 18:00 local time at Estadio Gigante de Arroyito with a semifinal berth at stake.
• River plans at least three adjustments, including the returns of Gonzalo Montiel at right back and Lautaro Rivero in central defense, with further tweaks under consideration.
• Captain Enzo Pérez is unlikely to feature due to stitches in his left knee, so Juan Portillo is positioned to anchor the midfield.
• Racing arrives after five matches in 16 days, with Juan Nardoni ruled out, Matías Zaracho likely unavailable, and Santiago Solari and Luciano Vietto considered doubtful.
• Marcos Rojo is eligible for the cup and could start for Racing, despite being unable to play Liga Profesional fixtures due to registration timing.
