The Bulls will miss Deng's scoring punch on Saturday. Chicago Bulls coach Tom Thibodeau said forward Luol Deng would miss Saturday night's game against the Detroit Pistons because of a left calf injury. The veteran coach said Deng would remain day to day and wasn't sure how long this latest injury will linger. Coach Tom Thibodeau said Deng has been dealing with the injury since the teams met in Detroit on Nov. 27, a 99-79 win. Chicago has lost six of eight. He was unsure this morning, he had tightness, they wanted to work on him and he just said it could be better in a couple days," Thibodeau said.
