BOSTON - The Boston Celtics announced today that they have extended the contract of Head Coach Glenn "Doc" Rivers. Per team policy, terms of the deal were not disclosed.

"Doc is a leader and I have all the confidence in the world in Doc as coach of the Celtics. With Doc as our coach we have the continuity that is crucial in the development of the franchise," Danny Ainge said, Celtics Executive Director of Basketball Operations.

Rivers just completed his third season with the Celtics and has amassed a record of 102-144.

In his first season with the Celtics, Rivers led the Celtics to their first Atlantic Division title since the 1991-92 season. During the 2005 Playoffs under Rivers, the Celtics battled with the Indiana Pacers but were ultimately defeated in the seventh game of the first round.

"I am happy to be the Head Coach of the Boston Celtics. Moving forward I am more determined to move this franchise in the right direction and I believe that I can do that," Rivers said.
