Leone Stars captain and skipper, Steven Caulker is highly likely to miss the all-important AFCON Qualifiers clash against West African rivals, Nigeria.
The former Tottenham defender sustained a knee injury in a final game with his English Championship side, Wigan Athletic.
Football Sierra Leone said the skipper has a 50-50 chance of playing the match.
Leone Stars will play against the Super Eagles on 18 June outside Sierra Leone after CAF rejected Sierra Leone’s application to play at the newly built Southern Arena in the second city Bo.
The match is set to take place at the Samuel Kanyon Doe Sports Complex in Monrovia Liberia.
Permutations have revealed that Leone Stars must win against Nigeria if they are to qualify for Ivory Coast next year.
Keister’s team last won against São Tomé and Principé after shockingly drawing with them in the first leg.
The result gave a glimpse of hope to Sierra Leone which now sits third in Group A with five points two shy of second place Guinea Bissau.
The Super Eagles lead the Group with nine points and a draw with Leone Stars will see them make it to Ivory Coast.
