The Boston Celitcs, Los Angeles Clippers and Phoenix Suns have agreed upon a three-team trade, sources tell RealGM.

Austin Rivers will be dealt to the Clippers with Reggie Bullock going to the Suns and Shavlik Randolph being sent to the Celtics.

Rivers was dealt from the New Orleans Pelicans to the Celtics as part of the three-team Jeff Green trade.

Rivers will be an unrestricted free agent in the offseason as the Pelicans declined their 15-16 option on his contract in October.

Dan Woike of the Orange County register reports that Chris Douglas-Roberts will be included the deal for the Celtics. Mark Murphy of the Boston Herald adds that Douglas-Roberts will be waived by Boston.
