Bulls coach Tom Thibodeau says guard Kirk Hinrich is sidelined for Monday's game against the Charlotte Bobcats because of "a compilation of things."
The chief concern is Hinrich's left knee, which cost him time earlier in December. Hinrich has battled numerous injuries this season.
Charlotte, which has lost 18 straight games, is without forward Michael Kidd-Gilchrist because of a scratched right cornea. He was poked in the eye during a 98-95 loss to New Orleans.
Nate Robinson is making his fourth start of the season for Chicago, and Jeff Taylor is starting for Charlotte.
