Thank you, but no thank you.

Sacramento Kings big man Marvin Bagley earned an invite to the second week of Team USA training camp in Los Angeles with his strong play last week, but a league source confirmed to NBC Sports Bay Area that the talented 20-year-old has decided not to accept the offer.

Marc Stein of the New York Times was first to report the news.

A member of the Select Team, Bagley was a surprise addition to the senior squad that will reassemble at the Lakers practice facility in El Segundo on Tuesday evening.

Bagley originally signed up for just a week of training, like teammate De’Aaron Fox, who has also made it to the second week of training. It's a huge commitment that plenty of players have walked away from this summer.

If Team USA makes it to the gold medal game on Sept. 15, they would have less than two weeks to recover and prepare for training camp, which begins in late September.

Fox and Harrison Barnes will continue on with the national team. The duo is part of the now 16 players vying for one of 12 spots on the team that will travel to Australia and then China later this month to take part in the FIBA World Cup.
