The Ohio State Buckeys will likely have linebacker Etienne Sabino back in the lineup on Saturday against Wisconsin, but judging by the weekly depth chart, we won't see much of him. Sabino does not appear anywhere on the linebacker depth chart in Monday's release.
That being said, it doesn't necessarily mean that he won't be playing. Depth charts aren't something a team is forced to follow, and this Ohio State team, under Urban Meyer, certainly might be one to engage in a little subterfuge. As noted by Luke Zimmerman of Land-Grant Holy Land:
Though it's not out of the ordinary for Meyer and co. to exhibit some gamesmanship in the weekly football pecking order document, if linebacker Etienne Sabino is going to come back and contribute, he's going to have to do so in spite of what the expected personnel would otherwise appear to be.
They've got the full depth chart over at that link. The linebackers listed include Joshua Perry, David Perkins (Sam LBs), Storm Klein, Zach Boren, Curtis Grant (Mike LBs), Ryan Shazier, Connor Crowell and Camren Williams (Will LBs). Again, anything can happen with Sabino if and when he makes his return, but according to the official depth chart, he's not likely to get a significant amount of playing time.
