Riley Leonard injury update

The Fighting Irish trailed 10-0 in the second quarter of the Orange Bowl, looking to get on the board with a championship appearance on the line. 

Soon after Notre Dame's offense took the field for another drive, Leonard took a big hit while attempting a pass. He went to the medical tent soon after to be evaluated for a head injury.

Per ESPN's Pete Thamel, Notre Dame's staff "appeared on the sideline to be administering a test for a concussion."

Steve Angeli replaced Leonard at quarterback, then leading the Fighting Irish to their first points of the game with a field goal.
