Ohio State sophomore cornerback Chimdi Chekwa will play Saturday against No. 3 Penn State (ABC, 8 p.m. ET) after leaving last week's game at Michigan State with a shoulder injury. Chekwa and junior Donald Washington have shared time at the cornerback spot opposite Malcolm Jenkins. Washington is expected to start against the Nittany Lions.
Northwestern released its injury report for the Indiana game, with the lone addition being middle linebacker Malcolm Arrington, who sustained a season-ending knee injury last week.
Here's the rundown of wounded Wildcats:
LB Malcolm Arrington, knee, out (season)
TE/FB Drake Dunsmore, knee, out (season)
DE Rejaie Johnson, shoulder, out (season)
CB Justan Vaughn, shoulder, out (season)
