Kevin Garnett practiced at full speed Saturday afternoon, his hyperextended right knee responding positively after Friday night's game, his first since Dec. 27.
Garnett played 30-plus minutes in the Celtics' 98-95 overtime win over Portland Friday night.
"It's good to have Kevin back," coach Doc Rivers said. "It's more important to see him feeling better after the game, going overtime, and (playing) a lot of minutes. It's a good sign for us.
"Someone asked if there was a minute restriction -- there wasn't. Again this was something totally different than last year's injury, that's why we were really not concerned about the minutes. Our whole concern with him, minute-wise, was more conditioning. It had nothing to do with the knee."
Garnett will practice Sunday in preparation for Monday's game against the Los Angeles Clippers.
