Bucks guard Michael Redd is not traveling with the team on a two-game trip because his left knee continues to bother him.
Redd strained a ligament in his surgically repaired knee in Milwaukee's win over Detroit on Oct. 31. Redd missed nine games, returned for three and has missed the previous two after soreness returned following a loss at Oklahoma City on Nov. 27.
The Bucks have been hit hard by injuries despite a 9-7 start.
Andrew Bogut (left leg strain) missed six games before playing in Monday night's win over Chicago and Luc Richard Mbah a Moute (left foot sprain) has missed eight straight games.
Luke Ridnour also hurt his left hamstring late in Monday night's win. He's day-to-day on the trip to Washington and Detroit.
