Rivers said Redick, who has been recovering from a broken right wrist and torn ligaments on the right side of his hand, is not close to returning yet.
When Redick was injured against the Sacramento Kings on Nov. 29, he was scheduled to be out six to eight weeks.
That would mean he wouldn’t return for about three more weeks.
The Clippers are saying that Redick possibly could come back Jan. 15 when the Clippers host the Dallas Mavericks at Staples Center or when the Clippers start a seven-game, 11-day trip in New York on Jan. 17.
Rivers said Redick hasn’t done much other than to shoot from “five feet.”
“Just talking to J.J., he just said the atrophy -- he's amazed how he doesn’t have any range of motion,” Rivers said. “That’s just natural when you have a cast on your wrist.”
Clippers rookie swingman Reggie Bullock, who is out with a sprained right ankle, has been shooting and participating some at practice.
Bullock could possibly return this weekend when the Clippers play at Dallas on Friday or at San Antonio on Saturday.
