COLUMBUS, Ohio (AP) Ohio State's All-American defensive end Nick Bosa will be out indefinitely after having surgery for a lower-abdomen injury.
Coach Urban Meyer said on his radio show Thursday that Bosa had surgery on a "core muscle." Meyer didn't provide a timetable for his return.
Jonathan Cooper is expected to start in Bosa's place opposite Chase Young in Saturday's game against Tulane. Defensive tackle Dre'Mont Jones also can play end, if necessary.
