The Super Eagles of Nigeria beat Guinea-Bissau 1-0 to progress to the last 16 of the 2023 Africa Cup of Nations.
Opa Sangante emphatically turned a Moses Simon cross into his own net in the 36th minute, after feeling compelled to intervene with Victor Osimhen lurking behind him.
Both sides had goals ruled out in the second half for offside, while Nigeria striker Victor Osimhen also had an effort disallowed for handball.
The result means the Super Eagles qualify in second place in Group A with seven points, behind Equatorial Guinea whose 4-0 destruction of hosts Ivory Coast leaves them with a far better goal difference.
Nigeria will face the second-placed side from Group C, which will be Senegal, Guinea or Cameroon, in the last 16 on Saturday .
