Nigeria striker Emmanuel Emenike will miss June's 2014 World Cup 
qualifiers and the Fifa Confederations Cup due to a knee injury.
The 25-year-old Spartak Moscow picked up the injury on 
Sunday, on his return from a long-term hamstring layoff, during a 
Russian Premier League match.
His club have confirmed that Emenike will be out of action for two months.
"It's a terrible setback for me because I was very happy to be back playing again on Sunday," he told BBC Sport.
