Ohio State quarterback J.T. Barrett suffered a right knee injury Saturday and couldn't finish the Buckeye's 31-20 victory over archrival Michigan on Saturday.
Someone, perhaps a photographer, bumped into Barrett while he was warming up before the game. That caused Barrett's right knee to lock up.
Barrett managed to play into the third quarter before the knee locked up on him again. Redshirt freshman Dwayne Haskins then came to the rescue, leading Ohio State on three scoring drives. Barrett was tackled by Wolverines linebacker Mike McCray with 6:07 left in the third quarter and his team trailing 20-14.
Barrett limped off the field with assistance and headed straight to the visitors' locker room.
Coach Urban Meyer promised an "all-out investigation" to determine what happened. "I'm so upset with myself," Meyer said. "It was a non-football injury. Too many damn people on the sideline and a guy with a camera hit him in the knee. I'm going to find out who."
Barrett, who vowed to play in the Big Ten title game against Wisconsin next Saturday, said his knee had locked up previously but wasn't expecting it to happen again before the game. "I don't know who it was. Michigan has a lot of people on our sideline, whether it be fans or photo people or whoever," he said. "He bumped into me and my knee kind of shifted in. Somebody tried to squeeze through (between him and the bench) and he hit me. He kept walking. I'm pretty sure he got a little nervous."
