Vikings left guard Ezra Cleveland was ruled out for Monday night's game against the San Francisco 49ers because of the foot injury he sustained last week against the Bears, so Dalton Risner will start for the first time since he signed a one-year, $3 million deal with the Vikings in late September.
Cleveland, who did not practice for the Vikings all week, will miss his first game since his rookie year in 2020.
"Ezra did everything he could, but we're going to allow that thing to get settled down and reassess him next week," coach Kevin O'Connell said.
Risner played the Vikings' final 10 offensive snaps against the Bears after Cleveland was injured. O'Connell said the fifth-year guard's experience showed up quickly with how easily he picked up the Vikings' scheme.
"Just a quieted, steady, productive performance without any kind of franticness or stress of, 'Hey, maybe I didn't get a rep on something.' That is a real beneficial thing to see," O'Connell said. "Ultimately, we knew at some point he'd be called upon, and that's why we went out and got him, to field overall great depth on that offensive line."
The 49ers will be without receiver Deebo Samuel, who will miss at least two games with a hairline fracture in his shoulder, coach Kyle Shanahan said. Left tackle Trent Williams (ankle) did not practice all week and is listed as doubtful. Christian McCaffrey (oblique), the NFL's leading rusher, returned to practice in a limited capacity Saturday and is questionable for Monday. Starting linebacker Dre Greenlaw (hamstring) is also questionable.
Rumph won't coach Monday night
Vikings defensive line coach Chris Rumph began a leave of absence from the team this week and won't coach on Monday night, O'Connell said.
Assistant defensive line coach Pat Hill will assume Rumph's responsibilities against the 49ers. Assistant head coach Mike Pettine, who's been working with the Vikings' outside linebackers with Mike Smith on a personal leave, will help on the defensive line, as will defensive assistant Imarjaye Albury.
