The hit occurred on the first play of Ohio State's drive with 7:06 remaining in the first quarter, when Smith-Njigba caught a four-yard pass from quarterback C.J. Stroud . Notre Dame's Cam Hart and Brandon Joseph were credited with the tackle, which ended out of bounds as Smith-Njigba's helmet flew off and he landed awkwardly. Smith-Njigba didn't immediately return to the game, but was on the exercise bike on the sideline and ran some sprints as he communicated with the team's athletic trainers. ESPN reporter Holly Rowe said on the broadcast Smith-Njigba was talking about the back of his left knee and his hamstring. Smith-Njigba played sparingly before returning to the injury tent in the second half. When he came out, he had a towel around his shoulders and appeared visibly upset. Smith Njigba led Ohio State with school-record totals of 95 receptions and 1,606 receiving yards last year. He finished Saturday with two catches for three yards.
