Hwang Hee-chan scored a stoppage-time winner to beat Portugal 2-1 and put South Korea through to the last 16 of the World Cup at the expense of Uruguay in a dramatic conclusion to Group H.

The Taeguk Warriors appeared to be heading out as they looked set to draw while Uruguay led Ghana elsewhere, but Hwang netted at the end to complete an incredible turnaround.

Ricardo Horta had put Portugal in front early on, but they failed to heed the warning posed by Kim Jin-su's disallowed goal soon after, with Kim Young-gwon deservedly getting South Korea back on level terms.

Portugal – who won the group anyway – coasted through the second half and South Korea took full advantage, with Hwang landing the decisive blow to spark bedlam and send Uruguay packing.
