Argentina's River Plate lose historic relegation fight
One of the great clubs of South American football, River Plate, have been relegated from the Argentine first division for the first time in their 110-year history.
River needed to win by two clear goals to escape dropping to the country's "B" league.
But the team managed only a 1-1 draw against Belgrano de Cordoba.
The match, held in River's stadium in Buenos Aires, had to be abandoned in the final minute, amid chaotic scenes.

Police fired water cannon up into the stands, following a pitch invasion by furious River fans.
And they had to escort players from both teams from the field, as home supporters hurled a barrage of objects over the perimeter fence.
The violence continued after the game, with clashes outside the stadium between hardcore fans and helmeted riot police, as helicopters hovered overhead.
More than 2,000 police had been deployed before the game in an unparalleled security operation for a club game.
Medical sources report that at least 25 people have been injured.
