BOSTON (AP) _ K.C. Jones, who guided the Boston Celtics to a pair of NBA championships in the 1980s, was named an assistant coach to M.L. Carr on Monday.

Jones replaces Don Casey, who left the Celtics to become an assistant to John Calipari in New Jersey.

The Celtics also announced Monday that Dennis Johnson was being promoted to the first assistant coach position.

Jones, 62, played on eight Celtics championship teams during his nine seasons with the Celtics.

After serving as an assistant coach with the Los Angeles Lakers' 1972 championship team, coaching the Washington Bullets into the 1975 NBA Finals, and serving as an assistant coach with the Milwaukee Bucks, Jones returned to the Celtics. He was an assistant coach from the 1978-79 season through 1982-83.

Jones succeeded Bill Fitch for the 1983-84 season, and with Larry Bird, Kevin McHale, Robert Parish and Johnson in his starting lineup, won the NBA title that season. The Celtics won again in 1986, while losing to the Los Angeles Lakers in the 1985 and 1987 Finals.

Jones also coached the Seattle Supersonics for two seasons, from 1990 to '92, and was an assistant to Don Chaney in Detroit for the 1994-95 season.

``His resume speaks for itself,'' Carr said in a statement. ``K.C.'s career is defined by his numerous championships. We're excited that K.C. will be rejoining the Celtics, bringing his unparalleled expertise, particularly on the defensive end.''
