Small forward Josh Howard, acquired as free agent after the NBA lockout ended, was set to make his first start Monday night for the Jazz.
Jefferson, bothered by inflammation in his right ankle, leads the Jazz in scoring at 17.9 points per game and is second in rebounding with a 9.0 average.
Bell had started every game this season but strained his right adductor Saturday against Sacramento. He is averaging 5.9 points and 1.4 rebounds a game.
Howard has averaged 8.9 points and 2.9 rebounds off the bench.
