Notre Dame is down its two best defenders. After the Fighting Irish lost All-American LB Jaylon Smith to a knee injury, Ohio State's Joey Bosa earned an ejection with a targeting penalty.
While chasing Irish QB DeShone Kizer, Bosa drove the crown of his head into Kizer's sternum. Tyvis Powell intercepted the errant pass, but it was called back after refs flagged Bosa for the hit.
Bosa was ejected from the game after the "leading with the crown of the head" targeting call was upheld.
Bosa, who leaves Ohio State as one of its all-time great defensive players, already told Urban Meyer he'll enter the 2016 NFL Draft.
After the ejection, Bosa crafted the following tweet:
I'm sorry, I love you buckeye nation.— Joey Bosa (@jbbigbear) January 1, 2016
