Celtics coach Doc Rivers said on Monday night that forward Kevin Garnett has been resting quite a bit since he last played in a game.

Rivers has held Garnett out since Dec. 28, when he logged 31 minutes against the Warriors.

"He's been shooting and stuff," Rivers said prior to Boston's game against Atlanta. "But no running or anything like that."

Garnett has missed Boston's last five games with a hyperextended knee and the timetable for his return isn't yet known.

He is averaging 15 points and 7.6 rebounds per game this season.
