PORTO ALEGRE, Brazil - Nigeria's coach says striker Michael Babatunde is undergoing surgery for a broken arm after being hit by a ball struck by a teammate in their World Cup match against Argentina on Wednesday.

Babatunde was stretchered off the pitch in a 3-2 defeat which did not prevent Nigeria from advancing to the second round from Group F.

Asked whether Babatunde might play again in Brazil, coach Stephen Keshi said: "We will see how it goes, but it's not good."

Babatunde, who plays for Ukrainian team Kryvbas Kryvyi Rih, was a surprise pick for the national team.

Nigeria will play the winner of Group E, which was winding up its matches later on Wednesday, in the last 16 on Monday.
