Luol Deng underwent an MRI of his sore left Achilles' tendon late Friday and is likely to miss Saturday night's game against the Kings with the injury.
"Lu's a huge part of our team on both ends," interim coach Jim Boylan said. "So if he's out a while, we'll have to make do with whatever we have to as far as a lineup change goes. Without Lu, we're obviously at a disadvantage."
Nocioni will replace him in the starting lineup.
Nocioni was one of several players Boylan talked to individually after Friday's brief film session and workout at Berto Center.
"I just tell Noce to relax because Noce really, really cares," Boylan said.
"And when he doesn't play well it bothers him. I appreciate that."
