Clint Dempsey is still deciding whether to wear a mask to protect his broken nose when the United States plays Portugal on Sunday.

Dempsey suffered a basal fracture on Monday during the Americans' 2-1 win over Ghana in their World Cup opener, though the U.S. Soccer Federation said he should be able to play despite the injury.

After the game, Dempsey was asked if he thought his nose had been broken by a first-half kick from Black Stars defender John Boye.

"I think so," he said, his nose clearly deformed as he spoke to reporters after the match.

On Tuesday, Dempsey's self-diagnosis was confirmed.

"Clint broke his nose," U.S. Soccer spokesman Neil Buethe said. "He's still trying to determine if he'll wear a mask, but it shouldn't affect him in any way."
