I was just reading this preview and it states:

The other issue is that Haskell Garrett, the other regular starter at tackle, is not going to be 100 percent regardless of whether he plays. Garrett has a knee injury that is considered substantial.

I've not heard anything about this anywhere.  A search here didn't turn up anything.  A search on Google turns up this site https://www.scacchoops.com/fb_injuries.asp?conference=Big+Ten -- not sure who they are.  Anyone have any info on this?
