Boston ? The Boston Celtics extended the contract of coach Doc Rivers on Thursday after a season in which the NBA’s most decorated franchise lost a team-record 18 consecutive games and finished with the second-worst record in the league.

“Doc is a leader and I have all the confidence in the world in Doc as coach of the Celtics,” Danny Ainge, the team’s executive director of basketball operations, said in a statement. “With Doc as our coach we have the continuity that is crucial in the development of the franchise.”

The team would not disclose financial terms or length of the extension.

Rivers is 102-144 in three seasons in Boston.
