According to Ferentz at Big Ten Media day in Chicago, Cooper still not back. He was hopeful, but in the same sense, it might not be realistic. He's not back yet. They haven't given up hope, but it just doesn't seem likely.
Will probably get more of an update on Duzey today at media day. In Chicago, Kirk basically said he's doing well, but that the next month as he gets more active, will be the key time frame. Still on track for September return, but it's unsure if it will be early/middle/or late.
