Williams (rest) has been ruled out for Monday's Las Vegas Summer League game against the Bulls, Sarah Todd of The Deseret News reports.
Monday's matchup will mark the second game of a back-to-back set, so Williams will receive a rest day. Darryn Peterson (rest) and Ace Bailey (back) will join Williams on the inactive list Monday, so guys like Orlando Robinson and Blake Hinson will be asked to step it up on offense.
