Paul Pierce remains undecided about continuing his NBA career this season.

"Depends on the day I talk to him. Paul has had the summer, he's gone back and forth," Doc Rivers said while back in Boston to host the annual ABCD Hoops Dream fundraiser at TD Garden. "I think he has a right to do that. I really do.

"Paul didn't have the best year last year. I don't think he wants to go out that way. So I think that's why he's working to try to come back. But he still may change his mind next week. So we just have to wait. I told him if I see him at training camp, I'm assuming he's playing."

Pierce has two seasons and $7 million remaining on his contract with the Clippers.

Rivers believes Pierce should sign a one-day contract with the Boston Celtics when he does finally decide to retire.
