CAIRO - Substitute Dominique da Silva scored seven minutes from time to salvage a precious 2-2 draw for Ahly against Zamalek in a nervy derby in the Egyptian Premier League Wednesday night . The defending champions Ahly pegged back twice with Geddo and Dominique canceling out an early own-goal from Sherif Abdul-Fadil and a fine strike from Hussein Yasser. The tension escalated after Ahly's second as Zamalek were furious when their opponents refused to put the ball out of play when two players were down during the build up to the goal. The draw doesn't help Zamalek who remain five points adrift of their arch-rivals, with three games remaining for both teams.
