South American football's governing body CONMEBOL said on Tuesday that the postponed second leg of the Copa Libertadores final between River Plate and Boca Juniors would be played outside of Argentina, in another country.
CONMEBOL said the venue for the match, to take place on "December 8 or 9" would be at an as yet undecided venue.
The original second leg clash between the two clubs at the weekend was postponed after Boca players were injured in an attack on their team bus by River fans with pepper spray, stones and sticks.
Paraguay, Brazil, and Italy have offered to hold the highly anticipated Superclásico. The first leg finished 2-2.
The two-week delay will give time for Boca players to recover from injuries suffered when their bus was attacked on Saturday en route to the final at River Plate's stadium. At least six players were injured, including Pablo Perez who suffered an eye injury. Others were affected by tear gas and pepper spray used by police to disperse the River fans.
Boca wanted River to be disqualified at a disciplinary hearing on Tuesday at CONMEBOL headquarters in Luque with the club presidents.
CONMEBOL President Alejandro Dominguez said "the conditions to play in Argentina are not right."
