Harbaugh said second-year cornerback Jaylen Hill might need hip surgery after he suffered a setback when he briefly tried to return to practice last week. Hill was attempting to come back from a torn ACL that put him on the physically-unable-to-perform list at the start of this season. … Wide receiver Quincy Adeboyejo also began the season on the PUP list after undergoing surgery on his upper leg. But Harbaugh offered some hope that he’ll return to practice. “I don’t think he’ll play this year, in the season,” he said. “But to get him back for three weeks of practice would be a bonus.” … Harbaugh, who’s from Ann Arbor, Mich., and is the brother of Michigan football coach Jim Harbaugh, guaranteed victory for the No. 4 Wolverines in their rivalry game Saturday against host No. 10 Ohio State. “I will say, this is the first year I’ve done that,” he said, chuckling.
