All 23 invited players have now linked up with the Super Eagles camp, with the squad completing their second training session on Wednesday evening at the Godswill Akpabio Stadium in Uyo.
The camp had initially opened with just three players on Monday, before 15 took part in Tuesday’s first training session.
Goalkeeper Stanley Nwabali arrived late Tuesday night, while Ademola Lookman and Cyril Dessers joined shortly after.
On Wednesday, the final arrivals — Samuel Chukwueze, Tolu Arokodare, Raphael Onyedika, Christantus Uche and Victor Osimhen — completed the squad.
Nigeria are under immense pressure to deliver in their next two fixtures, having won only once in their last six matches, the Eagles will host Rwanda on Saturday in Uyo before traveling to Bloemfontein to face South Africa’s Bafana Bafana three days later.
The Super Eagles’ qualification hopes also hinge on a potential points deduction for group leaders South Africa, who allegedly fielded an ineligible player against Lesotho in March.
As it stands, South Africa top Group C with 13 points from six matches, six ahead of Nigeria, who sit fourth on seven points. Rwanda and Benin Republic share eight points each in second and third, while Lesotho (six points) and Zimbabwe (four points) complete the standings.
After September’s double-header, Nigeria will conclude their campaign in October with a trip to Lesotho before hosting Benin Republic.
