After taking a 14-0 lead, Clemson kicked deep into the end zone. Kick returner Ahmaad Harris did not want to return the kick, but he forgot one important detail: Taking a knee to end the play.
Instead, Harris turned and flipped the ball to the referee who let the ball fall to the ground in the end zone. Harris seemed to realize the mistake he made, trying to signal for a fair catch after the ball was on the ground. But at that point it was too late as Clemson jumped on the ball for a touchdown.
Here is the play, via ESPN:
