Over 90,000 tickets have been sold for a two-game summer series between Team USA and the Australian Boomers as each team prepares for the FIBA World Cup.
The games, to be played at Marvel Stadium in Melbourne, would potentially pit Ben Simmons and LeBron James.
"I think he would like to play for coach Popovich, but of all the athletes, LeBron probably has the most going on both on and off the court. I mean we would love to have him ... who wouldn't, right? He played in the World Cup in '06, then didn't play in '10 and '14, but he enjoys the Olympics as well," said USA Basketball national team director Sean Ford.
Simmons hasn't confirmed whether he will play in the World Cup.
"He's in the middle of a season where they are legitimately hopeful of going deep into the playoffs, then there's contracts coming up and all sorts of things. There's no question we would love for him to play but at the same time we understand he's got a lot to figure out over the coming months. We're hopeful but I couldn't say (for sure) and I don't think anybody could," added Basketball Australia acting chief executive Paul Maley.
