The official spoke on the condition of anonymity because the deal was contingent on NBA approval and negotiations between Rivers and the Clippers over a new contract.
Rivers had three years and $21 million remaining on his deal with the Celtics, but he has expressed reluctance to coach through a rebuilding process. The 2008 NBA champions appear to be headed for one after losing in the first round of the playoffs this season.
The teams were also discussing a deal that would send Kevin Garnett to the Clippers, but NBA commissioner David Stern said he wouldn't approve a deal in which coaches were traded for active players.
