IOWA CITY, Iowa -- A few personnel updates before kickoff today at Kinnick Stadium.
Iowa wide receiver Colin Sandeman isn't on the field for warm-ups and likely will miss the game after sustaining a head injury last week at Michigan State. Sandeman has nine receptions for 70 yards this season.
Hawkeyes starting safety Brett Greenwood is warming up and should give it a go after hurting his neck in a nasty collision with fellow safety Tyler Sash last week.
Defensive end Adrian Clayborn looks fine after dealing with a knee injury. Freshman running back Brad Rogers is in uniform.
Indiana cornerback Donnell Jones is warming up with a brace on his right elbow, which he dislocated a few weeks ago. Starting linebacker Will Patterson also is warming up with a club on his left hand.
