Colombia's Daniel Muñoz scored the winning goal in the 76th minute, securing a 1-0 victory over Congo and a spot in the knockout stage of the FIFA World Cup.
Congo's goalkeeper Lionel Mpasi made five difficult saves in the first 20 minutes, but Muñoz's left-footed strike from inside the area proved to be the difference-maker.
Colombia's goalkeeper Camilo Vargas made several crucial saves in stoppage time, including a long-range strike by Nathanael Mbuku and a header by Chancel Mbemba.
Colombia now has six points from two matches in Group K, two ahead of Portugal and five clear of Congo.
