Iowa starting right guard Seth Olsen missed today's game and could be out for some time after injuring his ankle Wednesday on a non-contact drill at practice.
"It was just a blocking drill like we do every week frequently, and just one of those freak things," head coach Kirk Ferentz said. "I'm hoping he can make it back, but it's probably going to be a while. We'll see how next week looks."
Juniors Andy Kuempel and Rafael Eubanks rotated at Olsen's spot against Wisconsin. Iowa has a bye next week before visiting Illinois.
