Soccer-Libertadores holders Atletico Mineiro knocked out by Nacional

May 1 (Reuters) - Colombia's Nacional dumped holders Atletico Mineiro out of the Libertadores Cup on Thursday after substitute Jefferson Duque's goal two minutes from time earned his side a 1-1 draw in Brazil and a 2-1 win on aggregate. Nacional, who won South America's top club competition in 1989, won the first leg of their last-16 tie 1-0 in Medellin last week. Atletico went ahead in the 20th minute on Thursday when Diego Tardelli's shot came back off the bar and Fernandinho lifted the ball over a defender inside the box before rifling a volley inside Franco Armani's far post. The Colombian side equalised in the 88th minute when Atletico goalkeeper Victor failed to intercept a low cross from the left and Duque slid in at the far post to steer the ball home. "We're sad not to have qualified but at the same time the standard of the team's performance makes us optimistic for the rest of the season," Victor told Fox Sports. "We had two lapses in concentration and that cost us qualification," he said. In the first leg, Atletico conceded a goal in the third minute of added time. The result leaves only Nacional and Brazil's Cruzeiro as former champions in the last eight. Nacional now face Uruguay's Defensor Sporting in the quarter-finals, playing away in Montevideo in the first leg, while Cruzeiro are up against Argentine champions San Lorenzo.
