Isaiah Thomas is hell-bent on continuing his career in the NBA ... telling TMZ Sports his No. 1 -- and only -- plan right now is getting back into the Association.
"My only option is the league," Thomas said while out at LAX this month. "For sure."
The former Boston Celtics star, though, said right now there hasn't been much movement on his quest to land on a team. But, he told us he is staying patient.
"Just waiting it out," said the 34-year-old, who last played for the Charlotte Hornets in the 2021-22 season. "Staying ready to be on an NBA roster."
Of course, there are other pro leagues outside the NBA that Thomas could thrive in -- including the EuroLeague, the Australian National Basketball League and the Chinese Basketball Association ... but the two-time All-Star made it clear he wants to see NBA hardwoods only.
We also talked to Thomas about his former teammate, LeBron James, recruiting players for the 2024 Olympics following the country's loss in this year's FIBA World Cup semifinals ... and he told us if LBJ gets the guys he wants, it should be an easy win for Team USA.
"I have no doubt about that," he said. "We have the best talent in the world. The world is talented as well but they ain't messin' with us when we got our best team."
