The U.S. may face Australia in the World Cup without star Christian Pulisic

Players of the United States celebrate during their opening World Cup match, a 4-1 victory over Paraguay. The U.S. has an important match Friday against Australia.

The left winger Pulisic was key to the Americans’ fluid and effective attack in last week’s win over Paraguay. But he was kicked in the calf, left at halftime, and hasn’t trained with the team since.
