USA Basketball expects to have their full 12-man roster available for Sunday's matchup against France, the first game for both teams at the Tokyo Olympics.
Zach LaVine, who has been cleared to exit the health and safety protocols that stemmed from a coronavirus testing-related issue, will fly to Japan and rejoin the team on Thursday.
And the plan is that the three players from the NBA Finals - Khris Middleton and Jrue Holiday from the newly crowned champion Milwaukee Bucks and Devin Booker from the Phoenix Suns - will be in place on Saturday.
"I've got to celebrate this and then get on a flight and represent my country," Holiday said in Milwaukee, where the Bucks clinched the title.
The rest of the American roster worked out in Japan for the first time on Wednesday, a day after their flight from Las Vegas.
The likelihood remains that the team - which has already seen JaVale McGee and Keldon Johnson added in place of Kevin Love and Bradley Beal - will have just one full practice together before their games start to count.
"There's not a whole lot you can do when they get here the day before," US coach Gregg Popovich said on Wednesday from Tokyo. "Luckily, it's basketball. Try to keep it simple and take care of what we think we can take care of.
"The good thing is, they'll be in shape. I don't know how the plane's going to affect them, because it's not an easy flight."
The Americans arrived in Tokyo with just eight players from the 12-man roster because of LaVine's situation and the NBA Finals.
"We're looking forward to the challenge," Olympic veteran Kevin Durant said.
"Adding three guys, two champions, newly crowned champions and another guy who's been on that stage and knows what it's all about to win big games and play big games ... it's going to help."
