Stephen Curry is day-to-day because of a mild sprain of his left ankle.
Team USA said Curry's recovery was "progressing" but he remained day to day after suffering the injury on Wednesday.
"It hurts. To miss a great practice like this with the scrimmaging and all -- it's never great to have an injury, especially in a pressure situation like this," Curry said.
"I just have to make sure I get back this weekend."
United States coach Mike Krzyzewski has said that he would cut one player after the team's final exhibition match against Greece next week.
