Sunday’s rescheduled Copa Libertadores final second leg between Boca Juniors and River Plate has been postponed.
Violence had forced the match between the bitter Argentine rivals to first be delayed on Saturday.
The Boca Juniors team bus was attacked by River Plate fans on its way to the game at River’s Estadio Monumental.
The game was rearranged for Sunday at 20:00 GMT, 24 hours later than planned, but was postponed three hours before the new kick-off time.
A decision on whether the match will be rearranged for another date has yet to be announced.
