"&lt;p&gt;&lt;/p&gt;&lt;p&gt;Boca Juniors slumped to a 3-2 defeat at Argentinos Juniors in the Argentine championship on a weekend overshadowed by the postponement of River Plate's match because of hooligan fears.&lt;/p&gt;&lt;p&gt;River's game at home to Newell's Old Boys was called off on the orders of a judge on Saturday over worries about possible trouble between rival factions of the team's supporters.&lt;/p&gt;&lt;p&gt;The decision came after Gonzalo Acro, identified as a leading member of the hardcore River Plate supporters club known as \"Los Borrachos del Tablon, died on in hospital on Thursday, two days after being shot.&lt;/p&gt;&lt;p&gt;Police are investigating whether the incident is linked to a long-running internal feud in the group.&lt;/p&gt;&lt;p&gt;Boca, the reigning South American champion, was left with one point from two games after its defeat at Argentinos.&lt;/p&gt;&lt;p&gt;Pablo Ledesma gave Boca a 14th-minute lead but Alejandro Delorte equalized one minute later and Roberto Battian put the hosts ahead three minutes after the break.&lt;/p&gt;&lt;p&gt;Ledesma leveled for Boca with a 54th-minute penalty but Battian's second goal, in the 73rd minute, gave Argentinos the points.&lt;/p&gt;&lt;p&gt;Independiente, Estudiantes and Velez Sarsfield all have maximum points from their opening two games.&lt;/p&gt;&lt;p&gt;Diego Simeone's Estudiantes, missing midfielder Juan Sebastian Veron through injury, beat Gimnasia-Jujuy 1-0 with a late goal from midfielder Rodrigo Brana.&lt;/p&gt;&lt;p&gt;Independiente and Velez enjoyed 3-0 wins over Tigre and Olimpo respectively in matches played on Saturday.&lt;/p&gt;&lt;p&gt;Titleholder San Lorenzo picked up its first three points on Friday when it came from behind to win 2-1 at San Martin.&lt;/p&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
