Nigeria captain Joseph Yobo will miss a seventh successive game for his country after being ruled out of Saturday's African Nations Cup qualifier against Liberia in Calabar with a swollen knee, the Nigerian Football Federation said.
The 32-year-old centre back suffered the latest setback last weekend while playing for his Turkish club Fenerbahce against Besiktas.
Yobo is the country's most capped international with 87 appearances.
Nigeria forced a 2-2 away draw in the first leg of the final round tie in Liberia last month to put themselves in a strong position to qualify for the 2013 finals.
