The semi-final in Charlotte, North Carolina ended with Uruguayan players confronting Colombian fans in the stands as security personnel struggled to restore order. South American governing body CONMEBOL said it was investigating the incident.

With the majority of the 70,000-plus crowd cheering on Colombia from the start, Jefferson Lerma scored the winner after Uruguay forward Darwin Nunez had missed three good opportunities to put his side ahead.

The Liverpool striker had a great chance in the box in the 17th minute but curled his effort inches wide before a scuffed shot and another curling strike failed to find the target as he sat on his haunches wondering how he had missed.

Uruguay were made to pay for those missed chances when Lerma rose above the defence at a corner and squeezed his header past goalkeeper Sergio Rochet as James Rodriguez claimed his sixth assist of the tournament.
