The mayhem that swept River Plate's stadium in Buenos Aires following the famed Argentine soccer club's relegation to the second division left 89 people injured and is threatening the upcoming Copa America tournament.
The riots were sparked by rampaging fans humiliated by the team's demotion for the first time in its 110 years despite a history that includes more league titles than any Argentine club. In addition to those injured, police said 55 people were detained.
Fans were sprayed with high-power water hoses - inside and outside the stadium - with police using tear gas, rubber bullets and hand-to-hand combat in a futile attempt to control the rioting.
The stadium serves as Argentina's national stadium and is set to hold the Copa America final July 24. Argentina is the host nation for the Copa America - the South American national team championship - with play opening Friday in La Plata, 35 miles from Buenos Aires.

Bobsled builder leaves team
The group that built the United States' 2010 Olympic gold-medal-winning bobsled is parting ways with the national team.
Bo-Dyn Bobsled Project has built several U.S. bobsleds, including the "Night Train" that Steven Holcomb, Steve Mesler, Curt Tomasevicz and Justin Olsen guided to the first American Olympic bobsledding gold medal in 62 years at the Vancouver Games in 2010.
The Bo-Dyn Bobsled Project is headed by former NASCAR driver Geoff Bodine.
Boxer Mayweather is sued
A Nevada man claims boxer Floyd Mayweather Jr. directed his bodyguards to attack him at a Las Vegas casino last year after the man tried to take a photograph of the undefeated champion and asked about a fight with another star boxer, according to a lawsuit filed Friday in state court in Las Vegas.
The lawsuit alleges Mayweather's bodyguards attacked Anthony Cliff near a valet parking stand at the Palms Casino Resort on March 27, 2010, after Mayweather accused Cliff of "disrespecting" him.
Mayweather's bodyguards allegedly struck Cliff in the face, slamming his head into the ground. They then kicked him repeatedly in his back and side, the lawsuit says.
IOC issues social media rules
The International Olympic Committee has issued rules for athletes using social media at the 2012 London Games.
The IOC "actively encourages" competitors to "post, blog and tweet their experiences." But it warns that if rules are broken it can withdraw accreditation, shut down online operations and start legal action for damages.
Athletes can't use Twitter, Facebook or personal blogs for commercial or advertising purposes or share videos filmed at Olympic venues.
Rules prohibit comments about opponents, using "vulgar or obscene words or images" or the five-ring Olympic symbol.
The IOC has codified the rules in the aftermath of violations during the 2010 Winter Olympics.
FIFA separates political foes
FIFA says it will limit potential political issues in the 2014 World Cup qualifiers by separating Russia and Georgia, plus Armenia and Azerbaijan, in the European draw.
FIFA says it allowed UEFA's request to keep the former warring neighbors apart when qualifying groups are drawn July 30 in Rio de Janeiro, Brazil.
The teams were also kept separate in UEFA's 2012 European Championship qualifiers.
Armenia and Azerbaijan, which have no diplomatic relations, were drawn together in Euro 2008 qualifying, but the matches were never played. Russia and Georgia briefly warred in August 2008.
