Per Kirk Ferentz on his radio show:
OL Bryan Bulaga (undisclosed illness) is out. TE Tony Moeaki (ankle) and WR Derrell Johnson-Koulianos (hamstring) have a chance to play Saturday night at No. 5 Penn State.
“I don’t see Bryan playing this week, I think that’s pretty much a foregone conclusion,” Ferentz said. “The other two guys have a chance. We’ll see what happens. We still have roughly three days before kickoff here. We’ll see what happens. They’ve got some time. We’ll just see what happens.
