Nigeria captain Joseph Yobo is a major doubt for his side's decisive 2013 Africa Cup of Nations qualifying match against Liberia on Saturday on account of a knee injury.
"Yobo is most likely to miss Saturday's game after he suffered a knee injury while in action for his club, Fenerbache," said Ben Alaiya, press officer for the Nigerian national team.
"He has a less than 30 percent chance of playing against Liberia now."
Yobo played in last month's 2-2 first-leg draw between the sides in Liberia but was replaced by Efe Ambrose in the second half.
Injury has already prevented the experienced central defender from playing in a Nations Cup qualifying play-off against Rwanda and 2014 World Cup qualifiers against Malawi and Namibia earlier this year.© ANP/AFP
