Dunn also missed the team's season opener on Thursday, a loss to the Philadelphia 76'ers, after his wife gave birth to his son earlier this week.
Forward Denzel Valentine will also miss the game, as he continues to deal with a left ankle injury.
Without Dunn and Valentine, the Bulls struggled in the middle portion of Thursday's game, scoring just 35 points as the 76'ers eventually rode their way to a 127-108 victory in the game.
Zach LaVine did have a stellar opening night, scoring 30 points, but it wasn't enough as the Bulls got their season off to a losing start.
Tip-off is scheduled for 7 p.m. Saturday, and the game will air on NBC Sports Chicago.
