Ohio State's offensive line depth will be without one body for the foreseeable future.

Redshirt sophomore guard Demetrius Knox broke his foot in practice and is out for eight weeks, sources told Eleven Warriors on Friday. He underwent surgery Friday morning. Ohio State later confirmed the news.

Knox also broke his foot in February 2015 and missed all of spring practice that year.

A consensus four-star prospect from All Saints Episcopal High School in Forth Worth, Texas, Knox was the second-highest rated offensive lineman in Ohio State's 2014 recruiting class according to 247Sports, which ranked him as the 10th-best guard in the country that year. He competed for the starting left guard position this fall with true freshman Michael Jordan and redshirt freshman Matthew Burrell before ultimately losing to Jordan. However, Ohio State has listed Knox as Billy Price's backup at right guard on its depth chart all season.

The 6-foot-4, 308-pound Texan served as a key component to No. 2 Ohio State's special teams units both in 2015 and so far this fall. He also saw time on the offensive line late in wins against Bowling Green and Tulsa.

Knox is the second offensive linemen to suffer a significant injury this season, as junior college transfer Malcolm Pridgeon hurt his knee in August which sidelined him for three months.

The Buckeyes host Rutgers Saturday at noon.
