Cup qualifier nigeria loses 3 points fielding illegible player

It seems like you're referring to a recent development in the world of football (soccer).

So, to clarify, the Nigerian national team, which is participating in the African Cup of Nations (AFCON) qualifiers, has lost 3 points due to fielding an illegible player. This means that the team's points tally has been reduced by 3, which could potentially impact their chances of advancing to the next stage of the competition.

Can you tell me more about the situation? Who was the illegible player, and how did this come to light?
