The Copa Libertadores final second leg has been rescheduled for Sunday after Boca Juniors' bus came under attack outside El Monumental.

Boca travelled across Buenos Aires with the final tied at 2-2 after the opening game at La Bombonera, but deciding a winner will have to wait.

As the visitors' bus made its way towards River Plate's stadium it was showered with projectiles, with some smashing windows of the vehicle.

Eventually the bus arrived at the ground, but reports suggested three players had to be taken to hospital for assessment, while some were believed to have been affected by the use of pepper spray.

Discussions led to several delays in the scheduled kick-off time and the match has now been suspended until 1700 local time (2000 GMT) on Sunday.
