Michigan’s defense against No. 1 Oregon will be without a key player as cornerback Will Johnson will miss the Saturday matchup in Ann Arbor, Mich., due to an injury, CBS Sports/247 Sports and ESPN reported Friday night.Johnson got hurt on Oct. 19 during the Wolverines’ 21-7 road loss to then-No. 22 Illinois, and he didn’t play last week as Michigan beat visiting Michigan State 24-17.The injury was described as being to a lower leg, with CBS Sports reporting Johnson has a foot ailment.Asked about Johnson on Monday, Michigan coach Sherrone Moore said, “He’ll for sure (play again) this season. We’ll see how it works out this week and what he can do. So we’ll just let the doctors handle that. … Will has no plan of just shutting it down or anything like that.”If he could go out there, he would go out there in a heartbeat. I know that he’ll be back out there at some point this season, whether it’s this week, next week, whatever it is. And there’s zero doubt in my mind that he’s a competitor that wants to be out there with his teammates.”
