COLUMBUS (AP) — Two Ohio State freshmen have sustained knee injuries, with linebacker Kyle Berger facing surgery on the same knee he injured before his senior season last year.

Ohio State, which confirmed the injuries on Tuesday, said the Cleveland St. Ignatius High School product would have surgery next week.

Classmate Dylan Thompson, out of Montini Catholic in Lombard, Ill., also sustained a knee injury but he will not require an operation.

Both players are out indefinitely.

Team spokesman Jerry Emig also disclosed that third-year wide receiver Frank Epitropoulos from Upper Arlington will end his playing career to concentrate on academics in hopes of going to medical school.
