Though Danny Ainge plans to talk to Rajon Rondo about the guard’s decision to celebrate his 28th birthday in Los Angeles last Saturday while the team flew to Sacramento for a game against the Kings, the meeting might not take place for a week.

Ainge departed on a college scouting trip before the team’s return to Boston. Though the president of basketball operations still plans to discuss the issue with Rondo, he won’t return until next week.

A team source stressed that “it’s not that big a deal around here,” though Ainge hasn’t ruled out fining Rondo for not receiving official permission. The guard, who still is not playing on the second night of back-to-back games as he returns from ACL surgery, was not scheduled to play Saturday night in Sacramento. He chose to remain in Los Angeles for a birthday celebration that was attended by his wife, children and mother.
