Graham said that after last Saturday's 27-13 loss to SMU, it was determined that Kinne suffered a concussion after being hit in Tulsa's first offensive series.
"G.J. seemed dazed and out of it and was missing some reads and throws," Graham said. "He had a concussion in the first series and got hit in the back of the head. It's probably good that we did make a change there."
