Argentina striker Sergio Aguero is undergoing tests on a shoulder injury he suffered while scoring the goal that gave his country a hard-fought 1-0 win against Uruguay in Copa America Group B on Tuesday. After the game, captain Lionel Messi said, "[Uruguay] set out to play a tough game from the start, where they did not want to play much. Fortunately, Kun's [Aguero's] goal arrived, and after it was a battle, as that is what the game asked for. It was a physical duel, a fight, and we showed we can also play that way. We do not look for it, but we know how to play this way too." Argentina is now tied in its group at the top with four points from two games, alongside Paraguay, which beat Jamaica 1-0 on Tuesday.
