Mike Zarren turned down an offer to become general manager of the Philadelphia 76ers, two league sources said Thursday.

Zarren has served as the Celtics’ assistant general manager and team counsel for the past few years.

Danny Ainge hired Zarren as an unpaid intern in 2003.

"I don’t know all the details, but I know there was strong interest in Mike from Philly," said Ainge. "I don’t know why (he turned it down). You'll have to ask him."
