WALTHAM -- Doc Rivers had said that Kevin Garnet could return this week, possibly Friday, but that date has been pushed back. The Celtics coach said Thursday before practice that the earliest Garnett will play is Sunday against Washington.
"Heíll probably participate in shootaround [Friday], but Iím not going to play him [Friday], even if he wants to play," Rivers said.
Garnett has missed seven consecutive games with inflammation in his right ankle.
In other injury news, Paul Pierce, who turned his ankle Sunday against New York, did not practice and said he wouldn't have played if there was a game Thursday.
Pierce is expected to play Friday, as is Terrence Williams, who dislocated his right pinkie finger (on his shooting hand) during the first half of Wednesday's game against Detroit.
"They threw the ball, and I tried to put my hand out and get the ball," Williams said.
"As soon as the ball hit my hand, my finger just popped up that way," he added, pointing away from the rest of his hand.
Williams said he received X-rays during halftime and they came back negative.
Asked if he was disappointed that the injury happened when he was playing well, Williams responded, "You'd have to cut my hand off to get me to say I'm not going to play basketball."
