Serbia coach Radomir Antic says Subotic is the "natural" replacement for Lukovic, who was sent off in the 1-0 loss to Ghana in Group D. Subotic also came in after Lukovic's ejection in a 1-0 loss to Ghana.
Subotic spent part of his youth growing up in Salt Lake City and played for the United States Under-17 and Under-20 teams. But after coach Thomas Rongen left him off the roster for the 2007 Under-20 World Cup, he switched allegiance to Serbia, part of the Yugoslav nation when he was born in Banja Luka in 1988.
