Atletico Rafaela and Belgrano Cordoba cancelled each other out in Argentina's Apertura.

Second-placed Atletico could have closed the gap on runaway leaders Boca Juniors to six points with a victory but a goalless draw means they are eight points off the pace, two fewer than fourth-placed Belgrano.

Belgrano played for half an hour with ten men, after having Ribair Rodriguez sent off, but they held out for a point.

All Boys twice came from behind to deny Independiente. Matias De Federico opened the scoring for the visitors after ten minutes but Mauro Matos netted the first of his two goals nine minutes later.

Ivan Perez restored Independiente's lead nine minutes into the second half, but Matos was on target again seven minutes later.

Olimpo and San Lorenzo also shared the points after a 1-1 draw. Enzo Kalinski gave the visitors a fourth-minute lead but they had Juan Salgueiro sent off in the 32nd minute, and Julio Cesar Furch made Olimpo's numerical advantage pay off with the 73rd-minute equaliser.
