The Bulls, who won the game 83-81, were without Rose's services after the point guard complained about a problem in his surgically repaired knee.
"We wanted to see where he was today, but he wasn't as well as we would have liked," Thibodeau told reporters. "He still had the soreness. So we anticipated giving him time off.
"We view our training camp as the entire month. So if he needs a day, or a couple of days, we'll do that."
Rose had appeared in both of Chicago's previous two pre-season games before missing Saturday's match.
