Celtics coach Doc Rivers told WEEI in Boston on Thursday that there is a strong chance Kevin Garnett will miss the entire postseason.

"He's not going to be ready. After watching him practice, there's no way," Rivers said on WEEI-AM. "The way I saw him move today, I don't know if he'll be ready."

Garnett injured his right knee on Feb. 19, and has only played sparingly in four games since.
