The Celtics and Jeff Green have reached agreement on a multiyear deal, agent David Falk, and president of basketball operations Danny Ainge said told the Globe it will be official Wednesday.

Green, 25, missed all of last season after surgery to repair an aortic root but spent considerable time in Boston rehabilitating and even sat on the bench during some home games. That treatment and the fact the Celtics signed Green to a one-year $9 million deal before the injury and did not give him the $5.9 million qualifying offer and then allowed him to be an unrestricted free agent was critical in Green's return.

"We've reached agreement in principal for him to return," agent David Falk said. "You see a situation like Jeff's where there's a tremendous level of goodwill that been built up over the last year and half. I've got a long memory. I remember people who treat me well and I remember people who don't."

When asked if Green was official, Ainge told the Globe: "It's looking good. We intend to sign him. We anticipate it being (official) by Wednesday."

Green averaged 9.8 points and 3.3 rebounds in 26 games after coming over to the Celtics in the controversial trade that sent Kendrick Perkins to Oklahoma City.
