Several sources close to the situation said yesterday that Kendrick Perkins and Rajon Rondo would not participate in USA Basketball's minicamp in Las Vegas because of Perkins's wedding July 25 in Houston.
The USA Basketball mini-camp includes a meeting July 22, practice July 23-24, and an intrasquad scrimmage July 25.
Perkins is marrying his longtime girlfriend and Rondo is one of the groomsmen.
Perkins and Rondo originally thought the minicamp was in June, but after recently learning the actual date, they had representatives contact USA Basketball to turn down the invitation.
By not participating, Perkins and Rondo will have a hard time getting serious consideration to play for the US in the 2010 World Championships in Turkey and the 2012 London Olympics.
Celtics forward Glen Davis, however, will take part in the minicamp despite being invited to Perkins's wedding.
It may have to wait
While the Sacramento Kings have announced they will interview Celtics assistant
Tom Thibodeau for their head coach opening this week, the meeting could be pushed to next week because the NBA predraft camp in Chicago is this week. Thibodeau, who has already interviewed for the Sixers head job, is a free agent, but Celtics president
Danny Ainge said he has a contract awaiting him in Boston. "We'd like to have Tom back," Ainge said . . . Ainge will depart for Chicago today for a draft workout. He said the Celtics recently held a couple of small draft workouts in Waltham, and will hold a big one in late June. He attended a big workout in Houston, and will attend ones in Minnesota and New Jersey. "I need to know who everyone is, but I think I have a good grasp on it," said Ainge . . . Ainge said the Celtics have yet to decide whether to go back to Newport, R.I., for training camp this year.
