Watch: Notre Dame had only 10 players on the field for deciding play vs. Ohio State

Emmanuel Ocho of ESPN noticed something alarming to make matters worse for the Irish. Not only was Notre Dame missing a player on the game's final play, but they also had only 10 men on the field for the previous down, which resulted in an incompletion from Ohio State QB Kyle McCord.     

Notre Dame's defense had come up big earlier in the quarter, stifling Ohio State's Emeka Egbuka on an end-around try on fourth down with 4:12 to go. While the play seemed like a momentum shifter the Irish's way, the unit's gaffe with the game on the line quickly overshadowed it.
