Rivers contract extended

The Celtics signed Doc Rivers to a contract extension today, according to a league source. Terms of the deal were not initially disclosed.

Rivers, whose current deal expires at the end of the 2007-08 season, had made it clear that he didn't want to go into the final year of his contract without an extension.

His status with the team became an issue as the Celtics suffered an 18-game losing streak and finished with the second-worst record in the league (24-58) although they played a large part of the season without star Paul Pierce, who suffered foot and elbow injuries.

Rivers became the Celtics 16th head coach in April 2004. In his first season, the team was 47-35 and first Atlantic Division title since 1991-92.
