Varela replaces Danny for Portugal
Porto forward Silvestre Varela has replaced Danny in the 23-man squad picked by coach Paulo Bento for the decisive Euro 2012 qualifiers against Iceland and Denmark.
"Danny presented us with personal reasons that prevent him from being at the preparation camp and we accepted them," the Portuguese federation said in a statement.
Danny, who was on the scoresheet for Zenit St. Petersburg in last week's 3-1 Champions League win against Porto, has been regularly called-up to the national side since Paulo Bento took over last year.
Portugal, level with Denmark and Norway at the top of Group H, will play Iceland at home on Friday and then travel to Denmark four days later in their last two Euro 2012 qualifiers.
