CONMEBOL president Alejandro Dominguez rued a "sad day for South American football" and condemned those responsible for the violence which forced the suspension of the Copa Libertadores final second leg between River Plate and Boca Juniors.

Boca travelled across Buenos Aires on Saturday with the final tied at 2-2 after the opening game at La Bombonera, but its bus was showered with projectiles on the way to River's El Monumental stadium, 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.

CONMEBOL medical officials had deemed the injuries sustained to be "superficial" and approved the match to proceed despite Carlos Tevez's protests that Boca was unfit to play.

After discussions which led to several delays, the game was eventually suspended for 24 hours until 17:00 local time (20:00 GMT) on Sunday, and Dominguez called for those responsible to feel the full force of the law as a consequence.

"A sad day for South American football," Dominguez began in a series of tweets posted on his official Twitter account.
