World Cup-bound Nigeria conceded a late penalty and were held to a 1-1 draw by the Democratic Republic of Congo in a friendly in Port Harcourt planned to give them a fitting send-off to next month's tournament in Russia.
Nigeria, who head to Europe to continue their preparations with a game against England on Saturday, took a 15th-minute lead through Dutch-born defender William Troost Ekong.
But they gave away a spot-kick in the 78th minute which striker Ben Malomgo converted for the equaliser. Nigeria will also play a friendly against the Czech Republic before they head to Russia, where they face Croatia, Iceland and Argentina in Group D.
