Ikeme, who was diagnosed with acute leukaemia last summer, has been named an honorary member of the Super Eagles’ squad for Russia
The 31-year-old Wolves goalkeeper was informed that he had the disease last summer ahead of the Championship club’s promotion-winning campaign, and missed the entire season to receive vital treatment.
But ahead of Nigeria’s friendly against England at Wembley on Saturday, head coach Gernot Rohr said: “Until the last moment, there is a possibility of bringing in these players. Carl Ikeme will be our 24th player to the World Cup.”
Rohr admitted two weeks ago that the absence of 10-cap Ikeme – who was named Nigeria’s man of the match in their opening qualifier against Zambia in October 2016 – was his “biggest regret” heading into the tournament.
