Derrick Rose, the Bulls' leading scorer with 20.4 points per game, was out with an injured left wrist, while Luol Deng (18.0) missed his third game with a right calf strain. Third-leading scorer Joakim Noah continued to nurse a left foot injury.
Guard Kirk Hinrich also missed the game, serving a one-game league suspension after contact with a referee in Chicago's loss to Miami on Friday.
Meanwhile, Memphis center Marc Gasol also sat out with a strained neck muscle, missing his first game after playing in the first 149 of his NBA career.
Gasol, who averages 14.8 points and 9.5 rebounds, was hurt in Saturday's loss to the Denver Nuggets. Hasheem Thabeet, the second overall pick in last year's draft who was recently brought back from a stint with the NBA Development League's Dakota Wizards, started in Gasol's place.
Memphis did have one piece of good news. Ronnie Brewer, acquired in a trade deadline deal from the Utah Jazz, was active for the game after missing 13 games with a partially torn hamstring. He was hurt in his debut with Memphis against Miami on Feb. 19.
