Redick last appeared for the Clippers on Feb. 3 and has missed the team's previous four games because of the lower back injury.
Previously, Redick missed 21 games because of a broken hand.
It's a fairly significant blow to the Clippers as they make a push for one of the West's top two seeds down the stretch as Redick has been a very quality addition. On the season he's averaging 15.7 points and 2.2 assists in 30 games, shooting 39.6 from 3.
The Clippers have some depth with Jamal Crawford, but it certainly messes with their rotation. Redick is expected back for the postseason (this injury typically heals in 3-5 weeks), but it could play a part in where they fall in the seeding.
