Group 2

• Note: The other two Colombian teams that qualified for the tournament withdrew due to logistical issues, as CONEMBOL banned Colombia from hosting matches due to threats made by drug lords to referees in the previous tournament in 1989, with the murder of one of them interrupting the league without a champion being declared. The champion, Atletico Nacional of Medellín, had a bye to the second round as the current champion, but had to play their home games in Chile for this tournament.

Quarter-finals
