On Friday, teams started playing their second match in the group stage at the World Cup in Qatar. The opening game of the day between Wales and Iran is about to reach halftime, and the United States will be closely watching it.
At 8 a.m., host Qatar and Senegal will both try to earn points in Group A, followed by a match between Group A leaders Netherlands and Ecuador at 11 a.m. At 2 p.m., the day's main match features the Americans against England.
The ideal outcome for the United States would be a low-scoring tie or a victory for Iran in the first game on Friday.
The Americans' chances of making it to the knockout round would be significantly more difficult if Wales won, especially if they did so by a large margin.
If Qatar suffers another defeat, it may become only the second host nation to exit at the group stage, following South Africa in 2010.
On Saturday, Group C and Group D will each play four more games to prolong the World Cup. Find the most recent group rankings and the complete schedule here.
