Hill has a sprained shoulder and was kept out of Wednesday’s loss to Oklahoma City because of soreness.
ESPN was first to report Hill’s injury.
Hill’s setback is another shot to the Cavs, who are an NBA-worst 1-10 and will be without All-Star forward Kevin Love for another five weeks — and possibly longer.
While Hill is out, rookie Collin Sexton will likely stay in the starting lineup. The No. 8 overall pick made his first start against the Thunder and finished with a season-high 15 points, two rebounds and an assist in 42 minutes.
Cleveland coach Larry Drew has urged his veterans to be patient with Sexton while he develops.
