"He was feeling pretty good, so we'll see where we go with him today," Corbin said of Rush.
Williams, meanwhile, was said to have been pain-free after the session.
Last season, his first with the Jazz, Williams averaged 7.2 points and 3.6 rebounds in 73 games. He started for Corbin in 51 of those games.
Rush, acquired in a trade with Golden State, could provide much needed 3-point shooting for the Jazz upon his return. He shot 45.2 percent from beyond the arc in 2011-12, his last full season.
Corbin said Rush is still working his way back into shape.
"There's no way he's going to be in game shape," the coach said. "He's in better shape than when he first came to camp, but he's not in game shape just yet. He hasn't been up and down the floor in five-on-five with contact."
Mike Harris is still with the Jazz after seeing every other roster hopeful with a non-guaranteed contract cut, and Corbin doesn't want Harris playing scared.
"Until something change, you're with us and you should approach it that way," he said. "You can't keep looking over your shoulder. 'What's going to happen?' What's going to happen?' You just play."
Corbin said Harris, who did not see as much time in games this preseason as some, earned his roster spot in practice. The forward provides depth on the bench with Jeremy Evans out due to injury
Big man doubtful
Center Andris Biedrins suffered what the Jazz are calling a moderate left ankle sprain late in Monday's practice. The veteran big man is doubtful for Wednesday's regular season opener against Oklahoma City.
