COLUMBUS, Ohio — With just over two weeks remaining before its season opener, it appears No. 5 Ohio State already has suffered a devastating loss.

Two-time Big Ten offensive player of the year, quarterback Braxton Miller, considered among the top contenders for the Heisman Trophy, reportedly reinjured his throwing shoulder in practice Monday.

Ohio State officials declined to confirm Miller was hurt or speak to the severity of the injury, first reported by The Columbus Dispatch.

Miller, a senior, had missed all of spring practice after what was termed “minor, outpatient surgery” on his right shoulder. When workouts resumed in August, he had been held out of a scrimmage and a few practices after experiencing some soreness in the shoulder. But he proclaimed last week and again Monday that he was healthy and ready to go.

Coach Urban Meyer said last week that the soreness was an expected result of Miller’s throwing in practice.

“I anticipated this,” Meyer said. “I’ve dealt with guys with arm issues before, and we’re being very cautious. He could have practiced (in one of the workouts in which he didn’t play) but we’re in it for the long haul. So he’s right on schedule.”

Speaking briefly with reporters after Monday’s first practice of a two-a-day session, Miller said he was feeling fine and would be in good shape for the season opener Aug. 30 against Navy in Baltimore.

At the Buckeyes’ media day last week, Miller said his arm felt good and he was able to throw as much as he liked.

“After my rehab, I was throwing to guys at least four days out of the week,” he said. “Our timing and our situation-wise, when I get back in there it’ll be like I never left.”

If Miller is unable to play in the Buckeyes’ opener, redshirt freshman J.T. Barrett would likely get the start, backed by sophomore Cardale Jones.
