Kirk Ferentz was interviewed on 97.1 The Fan, a sports radio station in Columbus, OH, today. You can listen to the interview here. It's about 7 minutes starting around minute 27.
Ferentz talked a little about injuries particularly along the offensive line, Stanzi's development, Moeaki's health, and the defense tackle position. The big new, however, is that Ferentz is hopeful that Jewel Hampton will be back on the field next week. He uses his typical coach speak, but the situation sounds much better than it did last weekend after the open practice. If Hampton has a shot at practicing next week, then the odds that he'll be ready for UNI are more in his favor. If he's not going to be 100% though, I'd be comfortable holding him out until the ISU game.
Bulaga update:
Like Hampton, OT Bryan Bulaga has also been sitting out from practice with a knee "tweak" but if you look at the scrimmage pictures from today, the last pic clearly show #79 in full pads ready to go. There's no pictures of him in action, but he probably wouldn't be in pads if he wasn't feeling better.
