Globe NBA writer Gary Washburn reports that Celtics president Danny Ainge said today that coach Doc Rivers has agreed to a five-year contract extension to remain with the team.
The deal would keep Rivers in Boston through the 2015-16 season.
Adrian Wojnarowski of Yahoo! Sports reported via Twitter the deal was worth $35 million.
After the Celtics were eliminated from the NBA playoffs in five games vs. the Heat, Rivers confirmed he'd likely be back. Yesterday, he confirmed that a contract extension was "basically done."
Rivers had a one-year option to return, but indicated he wanted to get a new deal done quickly to allow the team top focus on improvements for next season.
"I wanted to get this out of the way so we can concentrate on the summer and free agency," Rivers said yesterday.
Rivers believes the Celtics can win another NBA championship if younger players are added to the roster. He also said having one of the Big 3 of Kevin Garnett, Ray Allen and Paul Pierce become a top player off the bench is a possibility.
"Depending on what we can get, that is something you would have to consider," he said.
