Nets' Kevin Garnett to miss fourth straight game with back injury

NEW YORK -- Kevin Garnett will sit out a fourth straight game because of back spasms Friday when the Brooklyn Nets visit Boston, missing his last trip this season back to his old home.

Garnett last played a week ago in Denver. He has since been sidelined for victories over Milwaukee, Chicago and Memphis.

Rookie Mason Plumlee has been starting at center in place of Garnett, who came to Brooklyn from Boston along with Paul Pierce in a draft-night trade. The Celtics played video tributes for both players when the Nets won in Boston in January.

On Thursday, the Nets signed Jorge Gutierrez from Canton of the NBA Development League to a 10-day contract. The Mexican guard played with the Nets in training camp.
