WALTHAM — For the first time since being sidelined by a hyperextended right knee, Kevin Garnett  returned to full practice on Tuesday. He took part in session, running up and down the court without a noticeable limp.
“It felt good,” Garnett said. “It felt good to be back with the guys today.”
Head coach Doc Rivers  said he will not allow Garnett to play on Wednesday night in Detroit when the team plays the Pistons but rather keep him on track for a Friday return when the Celtics  host Portland.
