BOSTON (CBS) – Boston Celtics principal owner Wyc Grousbeck joined 98.5 The Sports Hub’s Felger & Massarotti on Thursday, shedding some light on the future of head coach Doc Rivers.

One week ago, Celtics president of Basketball Ops. Danny Ainge said Rivers will return to coach the team next season. However, Danny never heard that from Doc, and Doc has yet to come out with his plans.

Though Grousbeck hasn’t heard it from Doc either, he’s also saying Rivers will be back next season.

“Our indications are that Doc is coming back. Typically — and it’s similar to Kevin Garnett, as an example — everyone is tired, burned out and frustrated (after the season ends); losing to the Knicks is something I never wanted to experience in my life,” said Grousbeck. “Everybody gets time to unwind and decompress. I expect Doc will help Danny with the draft workouts, to be in the war room June 27, and over the free agency period after that.”

“Between now and July 15 there is a lot of work to do to put the team together, and I expect Doc to be there.”

Grousbeck said Doc’s closest relationship on the team is with Ainge.

“I think Danny really spoke for him. They had been in communication and I think Danny went ahead and said it,” said Grousbeck. “I respect Doc too much to speak for him at this point; I hope he’s back. I’d be very surprised if he doesn’t, but he can change his mind on Labor Day. I hope he doesn’t do that.”
