What are college football's ejection rules?

Any player who commits a targeting foul will be disqualified from the game. If the targeting foul occurred in the second half, they'll also be disqualified from the first half of their team's next game. When a player is disqualified, they can remain on the sideline with their team (whereas an ejected player must leave the field of play).

If the conference appeals the next-game disqualification, the national coordinator of football officials will review the foul and decide whether the disqualification was warranted. If the disqualification is overturned, the player doesn't have to sit out the first half of the next game.

While targeting is the most talked about way to get ejected recently, there are plenty of other things that will get players and coaches tossed from a game.

Any players or coaches who participate in a fight will be ejected. If the fight takes place in the second half, they'll also be ejected for the first half of their next game.
